The process of salvation is provided to us in this scripture. Confession of sins unto God in true regret and desire for forgiveness. The physical baptism of water performed by a priest anointed by God for this purpose to prepare the heart of a person for restoration back unto God. The baptism of water unto repentance and acceptance of that repentance unto salvation. The baptism of the Holy Spirit unto salvation and fellowship with God. The presence of the Holy Spirit of God is for personal guidance and development needed for fostering holiness and discipleship according to the will of God concerning you.
