Salvation is purely an act of God in the spiritual realm.
Sure.
Its manifestation occurs here on earth, and is witnessed by our actions.
Paul calls it the "operation of God" and the "circumcision made without hands."
The "circumcision" made without hands is indeed an operation of God.
But without our actual baptism in Jesus' name for the remission of past sins, the operation of God is stymied.
Our obedience to Jesus, and to Peter, is essential.
This is the "baptism into Christ" that Paul speaks of in Romans 6. It is not water baptism but a spiritual baptism.
You are incorrect on both counts.
If either is the baptism of the Spirit...a gift from God...how is Rom 6:5 applied ?
Rom 6:5..."For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection:"
Where is this "planting" in baptism of the Spirit ?
Not immersed in water but immersed in Him, spiritually.
The unclean cannot be immersed in anything Godly.
Col. 10-13
"And ye are complete in him, which is the head of all principality and power:
In whom also ye are circumcised with the circumcision made without hands, in putting off the body of the sins of the flesh by the circumcision of Christ:
Buried with him in baptism, wherein also ye are risen with him through the faith of the operation of God, who hath raised him from the dead.
And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses;"
If the baptism of Rom 6 is the baptism of the Spirit, it must have allowed you to be free of sin.
Has it ?
Baptism using water in the name of Jesus Christ for the remission of past sins will ! (If the repentance from sin was true.)
It is written...“Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin.
For he that is dead is freed from sin.” (Rom. 6:6-7)
"Being then
made free from sin, ye became the servants of righteousness." (Rom 6:18)
"But now being
made free from sin, and become servants to God, ye have your fruit unto holiness, and the end everlasting life." (Rom 6:22)
