Romans 3:25
God presented Jesus as the atoning sacrifice [for our sins] through [our] faith in His blood [i.e., His death on the cross]. This was in order to demonstrate His justice when, by using forbearance, He passed over people's sins in previous generations.
1 John 2:1
My little children [i.e., dear ones], I am writing this to you so that you will not sin anymore. But if anyone does sin, we have Someone to go to the Father on our behalf; it is Jesus Christ, the [only] righteous One.
