Remission of sins that are past...

For all have sinned, and come short of the glory of God; Being justified freely by his grace through the redemption that is in Christ Jesus: Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God; To declare, I say , at this time his righteousness: that he might be just, and the justifier of him which believeth in Jesus. Romans 3:23-26

This is a big deal that most today refuse to see because it messes with OSAS (Once saved always saved)  to have this being past tense, which it is.

Most insist this is present and future tense, which it is not.
