Ezekiel 3:22
And the hand of the LORD was there upon me; and he said unto me, Arise, go forth into the plain, and I will there talk with thee. And the hand of the LORD was there upon me; and he said unto me, Arise, go forth into the plain, and I will there talk with thee.
Ezekiel 3:17-22 lays a solemn charge upon every believer to warn a brother who is in sin. That warning work is to bear plain warnings from God and to refuse to suffer a brother to go on in sin. It is to warn him of his danger and to tell him that death is the outcome and wages of sin. Failure to do this work comes from the watchman's own soul not being right before God.
The chapter teaches God's workers to depend entirely upon Him while faithfully doing the work He assigns. God Himself remains the instructor and the mighty worker in that labor. He uses human agents in the work without giving them any basis to claim the glory for themselves.
