1 John 2:1-2 (ESV)
My little children, I am writing these things to you so that you may not sin. But if anyone does sin, we have an advocate with the Father, Jesus Christ the righteous.  He is the propitiation for our sins, and not for ours only but also for the sins of the whole world.
“He is the propitiation for our sins, not only ours, but also for the sins of the whole world.” Let’s just bury this whole limited atonement then huh? Jesus didn’t just die for our sins, us who are elect, us who are members of the church. No he died for the sins of the whole world. In fact, the elect need to take comfort in this. The doctrine of limited atonement, coupled with a doctrine of election is a recipe for soul torture. I can know that I am elect, having been elected in baptism, having faith in the gospel that I have heard. But I can only know that Jesus Christ died for me, if I first know that he died for the whole world. I can only know he forgives my sins, that he is a propitiation for my sins, if he is the propitiation for the sins of the whole world, not just mine. If there is only one soul for whom Christ’s death was not propitiation, then that soul may as well be mine.
This gives us reason too to share the good news, to bring it to the world for whom he died. It pulls away from us any smugness, any reason for believing we are better, more loved, special etc.
