I'm debunking this whole, predestination thing to salvation. Predestination has nothing to do with one getting saved, but everything to do with those already saved.
Ephesians 1: 5 Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will, Having predestinated believes, those in Christ, unto the adoption. How does scripture define the adoption?
Romans 8:23 And not only they, but ourselves also, which have the firstfruits of the Spirit, even we ourselves groan within ourselves, waiting for the adoption, to wit, the redemption of our body. The adoption is something the believer has been promised. It is the future redemption of the body.
