A jealous God

Exodus 20v5 Thou shalt not bow down thyself to them, nor serve them: for I the LORD thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me;

The wickedness of idolatry

Deuteronomy 13v6-11 If thy brother, the son of thy mother, or thy son, or thy daughter, or the wife of thy bosom, or thy friend, which is as thine own soul, entice thee secretly, saying, Let us go and serve other gods, which thou hast not known, thou, nor thy fathers;
Namely, of the gods of the people which are round about you, nigh unto thee, or far off from thee, from the one end of the earth even unto the other end of the earth;
Thou shalt not consent unto him, nor hearken unto him; neither shall thine eye pity him, neither shalt thou spare, neither shalt thou conceal him:
But thou shalt surely kill him; thine hand shall be first upon him to put him to death, and afterwards the hand of all the people.
And thou shalt stone him with stones, that he die; because he hath sought to thrust thee away from the LORD thy God, which brought thee out of the land of Egypt, from the house of bondage.
And all Israel shall hear, and fear, and shall do no more any such wickedness as this is among you.

Ezekiel 8v7-18 And he brought me to the door of the court; and when I looked, behold a hole in the wall.
Then said he unto me, Son of man, dig now in the wall: and when I had digged in the wall, behold a door.
And he said unto me, Go in, and behold the wicked abominations that they do here.
So I went in and saw; and behold every form of creeping things, and abominable beasts, and all the idols of the house of Israel, pourtrayed upon the wall round about.
And there stood before them seventy men of the ancients of the house of Israel, and in the midst of them stood Jaazaniah the son of Shaphan, with every man his censer in his hand; and a thick cloud of incense went up.
Then said he unto me, Son of man, hast thou seen what the ancients of the house of Israel do in the dark, every man in the chambers of his imagery? for they say, the LORD seeth us not; the LORD hath forsaken the earth.
He said also unto me, Turn thee yet again, and thou shalt see greater abominations that they do.
Then he brought me to the door of the gate of the LORD's house which was toward the north; and, behold, there sat women weeping for Tammuz.
Then said he unto me, Hast thou seen this, O son of man? turn thee yet again, and thou shalt see greater abominations than these.
And he brought me into the inner court of the LORD's house, and, behold, at the door of the temple of the LORD, between the porch and the altar, were about five and twenty men, with their backs toward the temple of the LORD, and their faces toward the east; and they worshipped the sun toward the east.
Then he said unto me, Hast thou seen this, O son of man? Is it a light thing to the house of Judah that they commit the abominations which they commit here? for they have filled the land with violence, and have returned to provoke me to anger: and, lo, they put the branch to their nose.
Therefore will I also deal in fury: mine eye shall not spare, neither will I have pity: and though they cry in mine ears with a loud voice, yet will I not hear them.

1 Corinthians 6v9-10 Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind,
Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God.

Putting God first

Matthew 6v33 But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you.

Matthew 6v19-21 Lay not up for yourselves treasures upon earth, where moth and rust doth corrupt, and where thieves break through and steal:
But lay up for yourselves treasures in heaven, where neither moth nor rust doth corrupt, and where thieves do not break through nor steal:
For where your treasure is, there will your heart be also.

Luke 12v13-21 And one of the company said unto him, Master, speak to my brother, that he divide the inheritance with me.
And he said unto him, Man, who made me a judge or a divider over you?
And he said unto them, Take heed, and beware of covetousness: for a man's life consisteth not in the abundance of the things which he possesseth.
And he spake a parable unto them, saying, The ground of a certain rich man brought forth plentifully:
And he thought within himself, saying, What shall I do, because I have no room where to bestow my fruits?
And he said, This will I do: I will pull down my barns, and build greater; and there will I bestow all my fruits and my goods.
And I will say to my soul, Soul, thou hast much goods laid up for many years; take thine ease, eat, drink, and be merry.
But God said unto him, Thou fool, this night thy soul shall be required of thee: then whose shall those things be, which thou hast provided?
So is he that layeth up treasure for himself, and is not rich toward God.

Matthew 10v37-39 He that loveth father or mother more than me is not worthy of me: and he that loveth son or daughter more than me is not worthy of me.
And he that taketh not his cross, and followeth after me, is not worthy of me.
He that findeth his life shall lose it: and he that loseth his life for my sake shall find it.

Colossians 3v2 Set your affection on things above, not on things on the earth.

Decision-making tools

Philippians 4v8-9 Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things.
Those things, which ye have both learned, and received, and heard, and seen in me, do: and the God of peace shall be with you.

Greed and idolatry

Galatians 5v19-21 Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness,
Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies,
Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God.

Colossians 3v5-6 Mortify therefore your members which are upon the earth; fornication, uncleanness, inordinate affection, evil concupiscence, and covetousness, which is idolatry:
For which things' sake the wrath of God cometh on the children of disobedience:

The danger of greed

Romans 1v28-32 And even as they did not like to retain God in their knowledge, God gave them over to a reprobate mind, to do those things which are not convenient;
Being filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity; whisperers,
Backbiters, haters of God, despiteful, proud, boasters, inventors of evil things, disobedient to parents,
Without understanding, covenantbreakers, without natural affection, implacable, unmerciful:
Who knowing the judgment of God, that they which commit such things are worthy of death, not only do the same, but have pleasure in them that do them.

Isaiah 57v17 For the iniquity of his covetousness was I wroth, and smote him: I hid me, and was wroth, and he went on frowardly in the way of his heart.

Mark 7v20-23 And he said, That which cometh out of the man, that defileth the man.
For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders,
Thefts, covetousness, wickedness, deceit, lasciviousness, an evil eye, blasphemy, pride, foolishness:
All these evil things come from within, and defile the man.

Luke 12v15 And he said unto them, Take heed, and beware of covetousness: for a man's life consisteth not in the abundance of the things which he possesseth.

Ephesians 5v3-5 But fornication, and all uncleanness, or covetousness, let it not be once named among you, as becometh saints;
Neither filthiness, nor foolish talking, nor jesting, which are not convenient: but rather giving of thanks.
For this ye know, that no whoremonger, nor unclean person, nor covetous man, who is an idolater, hath any inheritance in the kingdom of Christ and of God.

Avoiding greed

Psalms 119v36-37 Incline my heart unto thy testimonies, and not to covetousness.
Turn away mine eyes from beholding vanity; and quicken thou me in thy way.

Hebrews 13v5 Let your conversation be without covetousness; and be content with such things as ye have: for he hath said, I will never leave thee, nor forsake thee.

Matthew 6v19-21,25-34 Lay not up for yourselves treasures upon earth, where moth and rust doth corrupt, and where thieves break through and steal:
But lay up for yourselves treasures in heaven, where neither moth nor rust doth corrupt, and where thieves do not break through nor steal:
For where your treasure is, there will your heart be also.
Therefore I say unto you, Take no thought for your life, what ye shall eat, or what ye shall drink; nor yet for your body, what ye shall put on. Is not the life more than meat, and the body than raiment?
Behold the fowls of the air: for they sow not, neither do they reap, nor gather into barns; yet your heavenly Father feedeth them. Are ye not much better than they?
Which of you by taking thought can add one cubit unto his stature?
And why take ye thought for raiment? Consider the lilies of the field, how they grow; they toil not, neither do they spin:
And yet I say unto you, That even Solomon in all his glory was not arrayed like one of these.
Wherefore, if God so clothe the grass of the field, which to day is, and to morrow is cast into the oven, shall he not much more clothe you, O ye of little faith?
Therefore take no thought, saying, What shall we eat? or, What shall we drink? or, Wherewithal shall we be clothed?
(For after all these things do the Gentiles seek:) for your heavenly Father knoweth that ye have need of all these things.
But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you.
Take therefore no thought for the morrow: for the morrow shall take thought for the things of itself. Sufficient unto the day is the evil thereof.
