No sin of a true believer was or is too vile to have been washed away on Calvary and forgiven by the Father. For "the blood of Jesus Christ, His Son, cleanses true believers from all sin — both the sins of their past, as well as all their present and future sins.
In addition, however, because that once-shed blood of Jesus shall never lose its power — it even now keeps on cleansing true believers from all sin (alias the ongoing transgression of God's most holy Law).5514 For "if any man
sin" or if anybody commits a sin — we [Christians] have an Advocate with the Father, Jesus Christ the righteous [Lawkeeper]; and He is the Propitiation [or the complete atoning Sacrifice] for our sins."5515
