Paul explains that the reason God saved us is to make us His own people and manifest us as His sinless, perfect children. God saved us in Christ, so that we may stand holy and without blame before His presence.
Some have asked if this means that the purpose behind saving us is only to make us holy. No! it is for His own glory that He saved us. The purpose of our salvation is to reveal the glory of God. To put on God's salvation and thanking Him is the highest praise that we can give Him.
Paul explains that God's glory is the ultimate purpose for saving us.
