In general, an abomination is something abhorrent or disgusting; things that are a cause for abhorrence or disgust.
Some translations of the Bible use this word often (such as the Amplified version), whereas others use it seldom or not at all.
A list of “abominations” (or detestable things) is given in Proverbs 6:16-19: a proud look, lying, murder, planning evil, running towards evil, a false witness, and stirring up trouble.
Key verse about Abomination: But whoever sacrifices a bull is like one who kills a person, and whoever offers a lamb is like one who breaks a dog’s neck; whoever makes a grain offering is like one who presents pig’s blood, and whoever burns memorial incense is like one who worships an idol. They have chosen their own ways, and they delight in their abominations (Isaiah 66:3, NIV).
A lifelong student of the Bible, Peter DeHaan, PhD, wrote the 700-page website ABibleADay.com to encourage people to explore the Bible. His main blog and many books urge Christians to push past the status quo and reconsider how they practice their faith in every area of their lives.
