Romans 6:4

We were buried therefore with him through baptism unto death: that like as Christ was raised from the dead through the glory of the Father, so we also might walk in newness of life.

'Buried therefore with him through baptism unto death' -a parallel is drawn between the burial and resurrection of Christ and the death and resurrection of the Christian ('that like as').

'Therefore' -as. natural consequence of death.

'Buried' -one more proof that the correct mode of baptism is immersion. (Colossians 2:12)

'Through the glory of the Father' -'by the Father's glorious power' (Wey) (Ephesians 1:19)

'So we also might walk in newness of life' -

'Walk' -'live an entirely new life' (Wey). (2 Corinthians 5:17); 'So we too might habitually live and behave in newness of life' (Amp). Lit., walk about, implying habitual conduct (Vincent p. 67)

'Newness' -2538. kainotes kahee-not'-ace; from 2537; renewal (figuratively): -newness. In life of. new quality (Gr. Ex. N.T. p. 633) (Romans 7:6)

In baptism one comes into contact with the benefits of Christ's death (a death designed to atone for sins-hence how could those baptized ever logically argue that they had the right to keep on sinning?); the result being. spiritual resurrection of the believer from 'dead in sin', to 'alive in Christ'. (Ephesians 2:1; Colossians 2:12). Hence baptism symbolizes the death, burial and resurrection of Jesus Christ. BAPTISM ISN'T THE outward sign of an inward grace, rather is the act that brings the believer into contact with benefits of Christ's death and resurrection.
