38And they shall be my people, and I will be their God: 39And I will give them one heart, and one way, that they may fear me for ever, for the good of them, and of their children after them: 40And I will make an everlasting covenant with them, that I will not turn away from them, to do them good; but I will put my fear in their hearts, that they shall not depart from me. 41Yea, I will rejoice over them to do them good, and I will plant them in this land assuredly with my whole heart and with my whole soul. 42For thus saith the LORD; Like as I have brought all this great evil upon this people, so will I bring upon them all the good that I have promised them. jeremiah 32
It seems to be a popular belief that repentance does not need to take place before conversion. Recently someone said in a forum that their pastor even said "repentance comes later".
