The glory of God is expressed in the person, character and nature of Jesus Christ. The cross is the ultimate expression of the glory of God on earth with reference to God the Father (His love, grace, mercy) and to Jesus Christ (His humble submission in obedience to the will and predetermined plan of God the Father). The outworking of the glory of God in the cross is salvation and eternal life to lost humanity. When born again believers live out the character of Jesus Christ, believers are glorifying God and reflecting His light. This is only able to be achieved through the ministry of the indwelling Holy Spirit.
