God Has Feelings
God is not just a robot that sustains the Universe for our entertainment.
God is a living person, who has feelings similar to us.
When the Bible says God was angry, people conclude that because God shows human traits, He must therefore have been made up by humans.
It's actually the opposite:
So God created man in his own image, in the image of God created he him; male and female created he them.
- Genesis 1:27 (KJV)
In other words, God has feelings, and therefore, in His image, so do we.
It hurts God when we break His commandments, and do evil.
And God saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually. And it repented the Lord that he had made man on the earth, and it grieved him at his heart.
- Genesis 6:5-6 (KJV)
God has waited a long time for us to repent:
The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.
- 2 Peter 3:9 (KJV)
God has put up with so much, and it has finally reached the point where God is no longer willing to sustain all this evil.
Judgment has finally come.
And he saw that there was no man, and wondered that there was no intercessor: therefore his arm brought salvation unto him; and his righteousness, it sustained him. For he put on righteousness as a breastplate, and an helmet of salvation upon his head; and he put on the garments of vengeance for clothing, and was clad with zeal as a cloak. According to their deeds, accordingly he will repay, fury to his adversaries, recompence to his enemies; to the islands he will repay recompence. So shall they fear the name of the Lord from the west, and his glory from the rising of the sun. When the enemy shall come in like a flood, the Spirit of the Lord shall lift up a standard against him.
- Isaiah 59:16-19 (KJV)
