Make kinsman redeemner Jesus Christ the propitiation of the sins of us, his elect, who believe in him (and never the perfidious Jews)

"My dear children, I write this to you so that you will not sin. But if anybody does sin, we have an advocate with the Father—Jesus Christ, the Righteous One.
He is the atoning sacrifice for our sins, and not only for ours but also for the sins of the whole world." 1 John 2:1-2, KJV
