God's glory is His goodness and character, not merely physical light, and the Shekinah that once rested in the temple now dwells in believers through Christ's Spirit. From 2 Corinthians 3:17-18, being transformed "from glory to glory" is best read as moving from one degree of glory to a greater, so glorification is a process under the New Covenant, culminating in sharing Christ's glory in the first resurrection (1 John 3:2). Where the Old Covenant hid and restricted access to God behind veil, court, and priesthood, Christ's Spirit in believers gives liberty to approach Him and receive what is needed to be changed into His image. Transformation requires cooperation: coming out of the world, ceasing unclean practices, and perfecting holiness in the fear of God (2 Corinthians 6:17-7:1). Righteous character becomes ingrained through practice (Hebrews 5:14), so that children come to look like their Father, as Jesus' contrast between Abraham's true children and the Jews who sought to kill Him shows. Sanctification and glorification describe the same process, stressing holiness and exaltation or witness respectively. Christ in us is the hope of glory (Colossians 1:27), a hope that grows as believers imitate and obey Him. Paul's prayer in 2 Thessalonians 1:11-12 is that God would perfect all goodness in them and that Christ's name be glorified in them through faith worked out by power.
