Baptism identifies the believer with the Father, Son and Holy Spirit.
“Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit,” Matthew 28:19
Baptism identifies the believer with Christ in His death, burial and resurrection. “In him you were also circumcised with a circumcision not performed by human hands. Your whole self ruled by the flesh was put off when you were circumcised by Christ, having been buried with him in baptism, in which you were also raised with him through your faith in the working of God, who raised him from the dead.” Colossians 2:11-12
“We were therefore buried with him through baptism into death in order that, just as Christ was raised from the dead through the glory of the Father, we too may live a new life.” Romans 6:4
Baptism is an act of conform-ability for the believer.
It is turning from our sin and selfishness to serve the Lord. It means placing our pride, our past and our sins before the Lord. It is giving the control of our lives over to God.
Peter replied, “Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins. And you will receive the gift of the Holy Spirit. The promise is for you and your children and for all who are far off—for all whom the Lord our God will call.” With many other words he warned them; and he pleaded with them, “Save yourselves from this corrupt generation.” Those who accepted his message were baptized, and about three thousand were added to their number that day.” Acts 2:38-41
Baptism is a public testimony-In Baptism; we stand before witnesses confessing our devotion to our Lord.
Death-“I have been crucified with Christ and I no longer live, but Christ lives in me. The life I now live in the body, I live by faith in the Son of God, who loved me and gave himself for me.” Galatians 2:20
Resurrection- 4 We were therefore buried with him through baptism into death in order that, just as Christ was raised from the dead through the glory of the Father, we too may live a new life.5 For if we have been united with him in a death like his, we will certainly also be united with him in a resurrection like his. Romans 6:4-5
10 The death he died, he died to sin once for all; but the life he lives, he lives to God. 11 In the same way, count yourselves dead to sin but alive to God in Christ Jesus. 12 Therefore do not let sin reign in your mortal body so that you obey its evil desires. 13 Do not offer any part of yourself to sin as an instrument of wickedness, but rather offer yourselves to God as those who have been brought from death to life; and offer every part of yourself to him as an instrument of righteousness. Romans 6:10-13
Cleansing- 21 “and this water symbolizes baptism that now saves you also—not the removal of dirt from the body but the pledge of a clear conscience toward God. It saves you by the resurrection of Jesus Christ,” 1 Peter 3:21
11 “And that is what some of you were. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God.” 1 Corinthians 6:11
