14. What does the Bible reveal concerning the character of God?
Answer: That He is kind, yet inflexible in the requirements of His law; loving and compassionate, yet terrible as a destroying fire against the rebellious and the guilty; forgiving towards offenses, yet jealous of the dignity, the glory, and supremacy of His Name. He is holy, and cannot look upon sin. He is wise, and cannot tolerate fools. He is true and faithful, and will destroy all that is false and perfidious. He is just and true and perfect -- at once the fountain of love and vengeance; the author of life and death; the source of reviving mercy and consuming fire. He is eternal, unchangeable, unsearchable, infinite, glorious in power and majesty -- the King immortal, the Possessor of heaven and earth, to whom alone is glory due.

Proof:

And shewing mercy unto thousands of them that love me, and keep my commandments. (Ex. 20:6).

The LORD is merciful and gracious, slow to anger, and plenteous in mercy. He will not always chide: neither will he keep his anger for ever. He hath not dealt with us after our sins; nor rewarded us according to our iniquities. For as the heaven is high above the earth, so great is his mercy toward them that fear him. As far as the east is from the west, so far hath he removed our transgressions from us. Like as a father pitieth his children, so the LORD pitieth them that fear him. For he knoweth our frame; he remembereth that we are dust. As for man, his days are as grass: as a flower of the field, so he flourisheth. For the wind passeth over it, and it is gone; and the place thereof shall know it no more. But the mercy of the LORD is from everlasting to everlasting upon them that fear him, and his righteousness unto children's children; To such as keep his covenant, and to those that remember his commandments to do them. (Psa. 103:8-18).

For our God is a consuming fire. (Heb. 12:29).

And it came to pass by the way in the inn, that the LORD met him, and sought to kill him. (Ex. 4:24).

Thou art of purer eyes than to behold evil, and canst not look on iniquity: wherefore lookest thou upon them that deal treacherously, and holdest thy tongue when the wicked devoureth the man that is more righteous than he? (Hab. 1:13).

The foolish shall not stand in thy sight: thou hatest all workers of iniquity. Thou shalt destroy them that speak leasing: the LORD will abhor the bloody and deceitful man. (Psa. 5:5-6).

And they sing the song of Moses the servant of God, and the song of the Lamb, saying, Great and marvellous are thy works, Lord God Almighty; just and true are thy ways, thou King of saints. (Rev. 15:3).

But the LORD is the true God, he is the living God, and an everlasting king: at his wrath the earth shall tremble, and the nations shall not be able to abide his indignation. Thus shall ye say unto them, The gods that have not made the heavens and the earth, even they shall perish from the earth, and from under these heavens. He hath made the earth by his power, he hath established the world by his wisdom, and hath stretched out the heavens by his discretion. When he uttereth his voice, there is a multitude of waters in the heavens, and he causeth the vapours to ascend from the ends of the earth; he maketh lightnings with rain, and bringeth forth the wind out of his treasures. (Jer. 10:10-13).

He is the Rock, his work is perfect: for all his ways are judgment: a God of truth and without iniquity, just and right is he. (Deut. 32:4).

Beloved, let us love one another: for love is of God; and every one that loveth is born of God, and knoweth God. He that loveth not knoweth not God; for God is love. (1 John 4:7-8).

And we have known and believed the love that God hath to us. God is love; and he that dwelleth in love dwelleth in God, and God in him. (1 John 4:16).

For we know him that hath said, Vengeance belongeth unto me, I will recompense, saith the Lord. And again, The Lord shall judge his people. It is a fearful thing to fall into the hands of the living God. (Heb. 10:30-31).

See now that I, even I, am he, and there is no god with me: I kill, and I make alive; I wound, and I heal: neither is there any that can deliver out of my hand. (Deut. 32:39).

I will heal their backsliding, I will love them freely: for mine anger is turned away from him. (Hosea 14:4).

His branches shall spread, and his beauty shall be as the olive tree, and his smell as Lebanon. (Hosea 14:6).

They have moved me to jealousy with that which is not God; they have provoked me to anger with their vanities: and I will move them to jealousy with those which are not a people; I will provoke them to anger with a foolish nation. (Deut. 32:21).

I will heap mischiefs upon them; I will spend mine arrows upon them. (Deut. 32:23).

Now unto the King eternal, immortal, invisible, the only wise God, be honour and glory for ever and ever. Amen. (1 Tim. 1:17).

For I am the LORD, I change not; therefore ye sons of Jacob are not consumed. (Mal. 3:6).

Great is the LORD, and greatly to be praised; and his greatness is unsearchable. (Psa. 145:3).

O LORD, thou hast searched me, and known me. Thou knowest my downsitting and mine uprising, thou understandest my thought afar off. Thou compassest my path and my lying down, and art acquainted with all my ways. For there is not a word in my tongue, but, lo, O LORD, thou knowest it altogether. (Psa. 139:1-4).
