The Sin of Omission

James 4:17

Showing verse 17 with surrounding context.

whereas ye know not what shall be on the morrow. What is your life? For ye are a vapor that appeareth for a little time, and then vanisheth away.

For that ye ought to say, If the Lord will, we shall both live, and do this or that.

But now ye glory in your vauntings: all such glorying is evil.

To him therefore that knoweth to do good, and doeth it not, to him it is sin.
