Salvation is spoken of as a finished transaction, described with "past tense" verbs. (Jn 1:12, Eph. 1:13)
When a person places thier faith in the redemptive sin atoning Death (sins wage paid), Burial & resurrection (God's receipt, payment received) of the Lord Jesus Christ.
Their salvation is final and complete. Salvation is not a process, it is an event. Christ described salvation as a birth because it is an instantaneous transforming event. You can't be UNBORN!!!!
