"To suppose that whatever God requireth of us that we have power of ourselves to do, is to make the cross and grace of Jesus Christ of none effect." - John Owen
Unconditional election is supported by scripture.
Ephesians 1:3-6 Praise be to the God and Father of our Lord Jesus Christ, who has blessed us in the heavenly realms with every spiritual blessing in Christ. 4 For he chose us in him before the creation of the world to be holy and blameless in his sight. In love 5 he predestined us for adoption to sonship through Jesus Christ, in accordance with his pleasure and will 6 to the praise of his glorious grace, which he has freely given us in the One he loves.
2 Timothy 1:9-11 9 He has saved us and called us to a holy life—not because of anything we have done but because of his own purpose and grace. This grace was given us in Christ Jesus before the beginning of time,10 but it has now been revealed through the appearing of our Savior,
Christ Jesus, who has destroyed death and has brought life and immortality to light through the gospel.
Question: "Monergism vs. synergism—which view is correct?"
....This brings us to the question of foreknowledge. Arminians will claim that foreknowledge refers to God foreknowing the faith of the elect. If that is the case, then God’s electing us is no longer based on the “good purpose of his will,” but rather on our being able to choose Him, despite our fallen condition which, according to Romans 8:7 is hostile to God and
incapable of doing so. The Arminian view of foreknowledge also contradicts the clear teaching of the passages mentioned above in support of unconditional election (Ephesians 1:4-5 and Romans 9:16). This view essentially robs God of His sovereignty and places the responsibility for salvation squarely on the shoulders of creatures who are wholly incapable of saving themselves.
