Luke 15:7-10

7 "I say to you that likewise there will be more joy in heaven over one sinner who repents than over ninety-nine just persons who need no repentance. 8 " Or what woman, having ten silver coins, if she loses one coin, does not light a lamp, sweep the house, and search carefully until she finds it? 9 "And when she has found it, she calls[her friends and neighbors together, saying, `Rejoice with me, for I have found the piece which I lost!' 10 "Likewise, I say to you, there is joy in the presence of the angels of God over one sinner who repents."

2 Cor. 7:9-10

9 Now I rejoice, not that you were made sorry, but that your sorrow led to repentance. For you were made sorry in a godly manner, that you might suffer loss from us in nothing. 10 For godly sorrow produces repentance leading to salvation, not to be regretted; but the sorrow of the world produces death.

Rev. 2:5, 16, 22

5 "Remember therefore from where you have fallen; repent and do the first works, or else I will come to you quickly and remove your lampstand from its place--unless you repent. . . . 16 `Repent, or else I will come to you quickly and will fight against them with the sword of My mouth. . . . 22 "Indeed I will cast her into a sickbed, and those who commit adultery with her into great tribulation, unless they repent of their deeds.

Rev. 3:3, 19

3 "Remember therefore how you have received and heard; hold fast and repent. Therefore if you will not watch, I will come upon you as a thief, and you will not know what hour I will come upon you. . . . . 19 "As many as I love, I rebuke and chasten. Therefore be zealous and repent.
