"Blessed be the God and Father of our Lord Jesus Christ, who has blessed us with every spiritual blessings in heavenly places in Christ, according as He chose us in Him before the foundation of the world, that we should be holy and without blame before Him in love." Eph. 1:3, 4; NKJ

Don't waste good time trying to understand why you were chosen in Christ for salvation, before He began to create anything. For whatever reason or reasons we were elected by God, let the mystery rest with Him. We know He chose us not because of any merit in ourselves. Well understand that had He not sovereignly chosen us we would not have been able to choose Him. All the spiritual blessings we have coming from heavenly places (God's realm) comes to us because we are in Christ, God's Beloved Son. It's a done deal; enjoy your day. We can be blameless, just not sinless.
