The reason we are born again is so that we can grow toward fullness. God has a way for all of this. The Bible explains it.  We go from glory to ever exceeding glory and from faith to faith until we reach the unity of the faith and of the knowledge of the Son of God.  The Body of Christ will come into total unity and walk as one man into the measure of the stature of the fullness of Christ, the manifestation of the sons of God and the redemption of our bodies.  See: Romans 8:18-23, The Full Maturity, Redemption Of Our Bodies, And Deliverance Of Creation From Bondage. & 2 Corinthians 3:18 Ephesians 4:15-16, Body Ministry By That Which Every Joint Supplies

This is not something about earning our salvation.  It is a part of our salvation.  It is the purpose of our salvation.  God has given us the ability to be born into His family and also the ability to grow up to fulfillment.

God has more for His people.  There are higher heights and deeper depths.   God has much more for you and for me. 

2 Corinthians 3:18 But we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the Lord.

Romans 1:17 For therein is the righteousness of God revealed from faith to faith: as it is written, The just shall live by faith.

Those who would worship God must worship in spirit and in truth.

Jesus said that we must worship God in spirit and in truth.

John 4:23-24 But the hour cometh, and now is, when the true worshipers shall worship the Father in spirit and in truth: for the Father seeketh such to worship him. God is a Spirit: and they that worship him must worship him in spirit and in truth.
