They that are of a froward (perverse) heart are abomination to the Lord: but such as are upright in their way are His delight (Proverbs 11:20)
Anytime we deviate from what is considered right or good and know we’re deviating from it, according to the Bible it’s sin, and God hates sin. Some actions people commit, they know that it’s wrong, but they will continue in it.
Our actions will either bring life or death. Abomination indicates a strong dislike for something; God has a strong dislike for sin and its an abomination to Him. Sin is not categorized, there is no little sin, big sin or in between. The wages of sin is death both physically and spiritually. This is why reading and studying the Bible is so important for Christians, it gives us the instructions of what is good and what is right as well as what is evil in the sight of God.
