Romans 1
26 For this cause God gave them up unto vile affections: for even their women did change the natural use into that which is against nature:

27 And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly, and receiving in themselves that recompence of their error which was meet.

28 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

What is a reprobate mind mind and do all unbelievers have it?

Forgive me for asking so many questions. I'm always seeking the truth of God's word.
