The true convert is a disciple, a person who has accepted and submitted himself to Jesus Christ, whatever that may mean or demand. The truly converted person is filled with the Holy Spirit and given a new nature that yearns to obey and worship the Lord who has saved him. Even when he is disobedient, he knows he is living against the grain of his new nature, which is to honor and please the Lord. He loves righteousness and hates sin, including his own.
John MacArthur
