" Repentance is only one part of our response to Christ (and even the strength to repent comes from God). But it is an essential part, for without it we cannot claim Christ is our Lord. The Bible says, “Godly sorrow brings repentance that leads to salvation and leaves no regret” (2 Cor. 7:10 NIV). "
