Romans 6:4 Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.
Notice that it says baptism into death and does not say baptism into water. Because we have been dunked into death with Christ and risen with Him we have our sins forgiven and are afforded the opportunity to come out of sin and walk in newness of life. Too often we dunk ourselves into sin rather than into Christ and we stay there.
Romans 6:8 Now if we be dead with Christ, we believe that we shall also live with him:
Ephesians 2:1 And you hath he quickened, who were dead in trespasses and sins; 2 Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience: 3 Among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others. 4 But God, who is rich in mercy, for his great love wherewith he loved us, 5 Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved;) 6 And hath raised us up together, and made us sit together in heavenly places in Christ Jesus:
Romans 6:11 Likewise reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Jesus Christ our Lord.
Colossians 2:20 Wherefore if ye be dead with Christ from the rudiments of the world, why, as though living in the world, are ye subject to ordinances, (rudiments: or, elements) 3:3 For ye are dead, and your life is hid with Christ in God.
