Repentance prepares our hearts for God. Repent means to change one's mind, to feel sorry and to move forward in a completely new direction. Sometimes God reveals his goodness to men to make them want to repent. Anointed preaching of God's word is often the means of causing us to want to repent.
Water baptism is a command.
Then Peter said unto them, repent and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost. Theree are over ten examples of water baptism in the Name of Jesus listed in the Bible. The first step is to thoroughly repent, secondly to be baptized in the Name of Jesus, and thirdly to believe that God will fill you with the Holy Ghost. Let the spirit of God submerge you . As you begin to surrender your life to the Lord, and praise the Lord from the depths of your heart, expect God to fill you with the Holy Ghost.
