How do we know that we are called to show forth His praise?

The doctrine of predestination as seen in Ephesians 1:4-5 indicates that God has chosen us in Christ before the foundation of the world. This choosing is a reflection of His sovereign grace, intended for the purpose of us being holy and blameless before Him. It highlights that our call and redemption are not based on our merits but solely on God's purpose and grace, which is to bless us with spiritual blessings so we may glorify Him. Moreover, we grow in grace and understanding through the Holy Spirit's work, revealing our identity as children of God who live to praise Him.
