The Scriptures declare that no one seeks God, so how can someone choose anything he doesn't see (John 3:3) or seek?
Rom 3:11 THERE IS NONE WHO UNDERSTANDS; THERE IS NONE WHO SEEKS AFTER GOD.
God supremely sovereign in all things including the people He chooses. Below are some Scriptures I pray that you will humbly ponder.
Pro_21:1 The king's heart is in the hand of the LORD, Like the rivers of water; He turns it wherever He wishes.
Psa 65:4a Blessed is the man You choose, And cause to approach You,
Psa 110:3a Thy people shall be willing in the day of thy power,
Jas 1:18 Of his own will begat he us with the word of truth, that we should be a kind of firstfruits of his creatures.
Joh 1:13 Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.
Rom 9:16 So then it is not of him who wills, nor of him who runs, but of God who shows mercy.
