When the Holy Spirit quietly moves in the heart of a repentant sinner and changes him into a son of God we call it the new birth. It is a marvelous work of grace that humanly cannot be explained but that must take place if you want to reach Heaven.
Is your life dominated by selfishness and pride? Whether or not you are a believer, discover new life in Christ by, like Zacchaeus, humbly coming to the Savior.
