Read Romans 1:26-32

Furthermore, just as they did not think it worthwhile to retain the knowledge of God, so God gave them over to a depraved mind, so that they do what ought not to be done. They have become filled with every kind of wickedness, evil, greed and depravity. - Romans 1:28-29a (NIV)

Since the Fall, Satan has continued to draw people toward independence from God—that is, disobedience. Eventually God gave us over to our depraved minds, and bad things happened—and we did it to ourselves. But when we realize, by God’s grace, what the cause of our problems really is, He is there to welcome us back to fellowship with Him. Praise God!
