1) An infinite loathing and intense disapproval of the heart and life of the person who is wicked. It is a feeling of the strongest opposition to the will and character of the person who is opposed to His own character of perfect love, righteousness and holiness.
2) God cannot behold sin without feelings of anger towards it. His anger is an intense hated of evil. It is hatred of all wrong doing.
3) God is not angry merely against the sin apart from the sinner, but against the sinner himself. There is an absurd view that is willing to acknowledge that God is angry with sin but not with the sinner. He hates theft but is pleased with the thief; hates adultery but is all loving towards the adulterer, etc. God's love towards sinners is a call to repent and be saved; not an excuse to continue in sin.
The sinner himself is the person who offends God and it is the sinner himself who will be sent to Hell. It is the sinner himself, not the sin, that is ultimately punished. The sinner is punished because of his sin, but it is the lost person who bears the wrath of God. Sin has no moral character apart from the sinner.
4) The anger of God against the wicked implies all that properly belongs to anger when it exists with good reason. We should note that God’s anger is perfect, just as God is perfect.
