Hopefully making theology simpler to understand! (2 Corinthians 1:12)

There are six things that the Lord hates, seven that are an abomination to him: haughty eyes, a lying tongue, and hands that shed innocent blood, a heart that devises wicked plans, feet that make haste to run to evil, a false witness who breathes out lies, and one who sows discord among brothers.
Proverbs 6:16‭-‬19, ESV

The greatest abomination according to God? Our selfish, destructive sin. Not so much any particular sin, just sin in general.
Turn from sin to salvation in Christ.
