I notice that predestination is almost entirely a Romans and OT sola scriptura. Have you noticed this too?
Not really. God's sovereign choices are all over Scripture.
In the OT, God chose Israel. He chose David over His brothers. He chose Jeremiah from his mother's womb. He chose Moses. In the New Testament, He chooses Mary. He chooses each disciple. They aren't pursuing Him, He chooses them. Why not others? Because it wasn't His will. Predestination is found in Romans, Ephesians, Revelation, 1 Corinthians, 2 Timothy etc.,
Romans deals a lot with it because Romans is basically one big theology book. The other books are dealing with specific issues the churches were facing.
LOL. Only to someone who hasn't read the rest of the Bible.
Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will, To the praise of the glory of his grace, wherein he hath made us accepted in the beloved. In whom we have redemption through his blood, the forgiveness of sins, according to the riches of his grace; Wherein he hath abounded toward us in all wisdom and prudence; Having made known unto us the mystery of his will, according to his good pleasure which he hath purposed in himself: That in the dispensation of the fulness of times he might gather together in one all things in Christ, both which are in heaven, and which are on earth; even in him: In whom also we have obtained an inheritance, being predestinated according to the purpose of him who worketh all things after the counsel of his own will" -- Ephesians 1:4-11"According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love:
