He creates in those sinners whom He has forgiven new and good hearts. We have all read in the newspapers of the remarkable operations which some skilled surgeons have performed on people whose physical hearts had stopped functioning. They take out the bad heart and put in its place a good heart taken from someone who had just died of an injury. This is indeed wonderful, but God has done something yet more wonderful. For by His Holy Spirit He has given new spiritual hearts to those who have believed on Christ so that they will thereafter hate what is evil and love what is good, and be able to love God and love their neighbor as God commanded.
Christians are people who have new hearts.
This does not mean, of course, that Christians are sinless for the only man who ever lived a sinless life is Christ Himself. But Christians do not want to sin, and they try with God 's help not to sin, and to obey God in everything. And when they do unwillingly sin, they at once confess it to God and repent and endeavor not to sin again. Therefore, we see that those who have the new hearts that God has given them have been truly born again, and are new men in Christ. A Christian is one who has everlasting life.
