St. Paul used such imagery to show certain aspects of Salvation to his contemporaries who had been deceived into believing that by obeying a few of the "rules" taught within the covenant of Moses (Law), that they were righteous (self-righteousness/sinful pride). But the whole picture of Salvation remains beyond intellectual comprehension, because it involves the unfathomable, indescribable personal experience of all believers who come into Communion with God, in the Holy Spirit. Salvation is not "defined". It is not "explained". It is not a "forensic, scientific, mathematical formula". It is a deep mystery to be beheld by those who come face to face with the Living God, by grace. Paul's words convey metaphorical imagery that point to a Love, a Glory, so inexpressible that it leaves us without any words, but with only songs of praise bursting forth from joyous hearts, and with holy tears. This is by the revealing of Christ, Who shows us the Father, by the Holy Spirit. To become One with the Holy Trinity is salvation. It is Eternal Life, to know (Love) the only God, and Jesus Christ Whom He sent. There is far more to our salvation than can be told by discussing merely one aspect of the Atoning work of Christ, of which there are even yet more aspects revealed in Scripture.
