If I covered my transgressions as Adam, by hiding mine iniquity in my bosom: - Job 31:33

For as in Adam all die, even so in Christ shall all be made alive. - 1 Corinthians 15:22

    If a man is covered (paid in full on the cross of Calvary) by the works and merits of Christ alone, salvation by the imputed righteousness of Christ alone, then he is made alive (a new creature IN Christ), and if a man is trusting in his own works and merits then he “shalt surely die”.  A man cannot hide his iniquity from God in his own bosom “as in Adam”. Only by  grace is God’s justice satisfied and is a sinner justified by the imputed righteousness of Christ alone.

   In this respect as well only those chosen in Christ by God will ever, by God’s power in His deliverance and justification of His saints by the blood of Jesus Christ, see their sinfulness and be born again a new creature in Christ by the grace of God. The old, “Adam” is passed away.  Those chosen before the foundation of the world in Christ receive in time the seal (Spirit of promise) that they have been given by God’s grace “all things” in Christ Jesus alone.  Imputed with Christ righteousness, and Christ paid the debt of God’s elect in full  by bearing those sins on the cross of Calvary, making an “end to sin”.  A perfect and unblemished, one time sacrifice by which Christ’s blood reconciled “all that the Father hath given him” unto God and satisfying God’s justice.

Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new. - 2 Corinthians 5:17
