'Sins' in the Bible

Flee from fornication. Any other sin that a human being commits lies outside the body; but he who commits fornication sins against his own body.

Whoever, therefore, in an unworthy manner, eats the bread or drinks from the cup of the Lord sins against the body and blood of the Lord.

For I repeated to you the all-important fact which also I had been taught, that Christ died for our sins in accordance with the Scriptures;

and if Christ has not risen, your faith is a vain thing--you are still in your sins.
