What does the Bible say about being fully blessed of God?

Ephesians 1:3 highlights that believers are blessed with all spiritual blessings in heavenly places in Christ. This indicates that our spiritual endowment and acceptance before God come through our union with Christ. The comprehensive scope of these blessings encompasses our salvation, justification, sanctification, and ultimately glorification, all of which are secured by God's sovereign grace, signifying that our acceptance is based solely on the merits of Jesus Christ and not our works.
