All excellent examples of passages where the Calvinist reads their doctrine into the text.Eph 1:3-6 Blessed be the God and Father of our Lord Jesus Christ, who has blessed us with every spiritual blessing in the heavenly places in Christ, just as He chose us in Him before the foundation of the world, that we should be holy and without blame before Him in love, having predestined us to adoption as sons by Jesus Christ to Himself, according to the good pleasure of His will, to the praise of the glory of His grace, by which He made us accepted in the Beloved.
On he omniscience of God:
1 John 3:20 in whatever our heart condemns us; for God is greater than our heart and knows all things.
Psalm 139:4 Even before there is a word on my tongue, behold O Lord, you know it all.
Matt 10:30 But the very hairs of your head are all numbered.
Psalm 147:4 He counts the number of the stars; He gives names to all of them.
Hebrews 4:14 ANd there is no creature hidden from His sight, but all things are open and laid bare to the eyes of Him with whom we have to do,
Isaiah 46:9-10 "Remember the former things long past, for I am God, and there is no other; I am God, and there is no one like Me, declaring the end from the beginning, and from ancient times things which have not been done, saying, 'My purpose will be established, and I will accomplish all My good pleasure.
None of these teach omniscience in the classical sense of the term.
