In Romans 8:29-30 and Ephesians 1:3-6. Romans 8:29-30 declares: "For [those] whom He foreknew, He also predestined to be conformed to the image of His Son, that He might be the firstborn among many brethren.
Moreover, [those] whom He predestined these He also called, whom He called these He also justified; and whom He justified, these He also glorified".
This is who I am and who you are if you choose it or not. -Many are called but few will receive God's Son for their own salvation.
Ephesians 1:3-6 teaches: '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 blameless before Him in love, having predestined us to adoptions 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 has made us accepted in the Beloved"
Imagine all the blessings, promises and peace some will miss just because they refuse to believe!
