Ridge, I went back to check that passage and didn't see "in order" in it. It said "...and the blood of Jesus Christ His Son cleanses us from ALL SIN." I added caps for emphasis. I mean you no offense. Perhaps I am just understanding it differently.
The IF at the beginning means there is a condition required.
"The Heavens declare the glory of God;and the firmament sheweth his handiwork" Pslam 19:1
