Our Lord opened the gates of heaven on the cross. He did not guarantee anyone’s entrance. Entrance must be earned. God the Father is Just and this is justice.
Welcome to the forum. But, be warned. You now have the problem of 1 Peter 5:8, but you are not alone. All of we Christians share in this struggle.
Do you mean 1 Peter 5:10 (Douay Reims) ... Jesus, after you have suffered a little will himself perfect you and confirm you and establish you ...?
Peter is saying that naturally we can’t do the works alone - He (the Lord) will help us because the devil is around to devour.
It does not mean that we are absolved of responsibilty for our own salvation.
Thanks- this is a great forum although this thread should be broken down because it has become unwieldy.
