“And even as they did not like to retain God in their knowledge, God gave them over to a reprobate mind, to do those things which are not convenient;”
King James Version (KJV)
1:28 God gave them up to an undiscerning mind - Treated of, #Rom 1:32|. To do things not expedient - Even the vilest abominations, treated of verses #Rom 1:29 |- 31.
Ro 1:28 God gave them over to a reprobate mind. A thought is repeated here that has already been hinted, and is often taught in the Scriptures. The man who turns from the truth will be allowed to have his way, will fall deeper and deeper into error, and will reap all the evil consequences of loving darkness rather than light. Those who hate the truth are "given over to a reprobate mind". A reprobate mind is one rejected of God. Which are not convenient. Not decent, or honorable.
