God’s goal is His own glory.
What is “the glory of God” or “God’s glory” ?
The glory of God is basically “the intrinsic worth and character of God”, or “His weightiness”, which is based on the Hebrew word for glory, “Kavod” or כבד – which points to “weight”, “influence”, “impact”, “honor”. The context of God’s glory seems to described in the Bible of trying to describe the brightness and shining of blinding light of a vision someone who is sitting on a throne high, and lifted up, in exaltation. (Isaiah chapter 6, Ezekiel chapter 1, Revelation chapters 4-5.)
See also: Hebrews 1:3; John 1:14, 18; 2 Corinthians 4:6 are communicating the truth that Jesus Christ explains (exegetes) God Himself in the flesh.
The glory of God is not only about describing God’s character, and His impact; but it is also the response that is the proper response to God – to give Him glory and honor; to praise and worship Him.
God’s goal of being glorified is expressed in 2 ways:
1. God’s justice and holiness in judging sin
2. God’s love in saving sinners
Everything in the Bible and History is for the glory of God and history is moving toward the ultimate end of the glory of God in all things. (Ephesians 1:11, with verse 6, 12, and 14 where the phrase “to the praise of His glory” is repeated three times) Even when God judges sinners in hell or the lake of fire (Revelation 20:10-15; Mark 9:47-48; 2 Thessalonians chapter 1) that is God’s justice and holiness expressed by His just wrath on sinners for eternity, and God gets glory for that.
God also gets glory from showing His perfect love in saving sinners in all nations from sin and hell; and part of the preaching of the good news presupposses that we need a savior from sin, because our sin has condemned us before a holy God and so we humans must repent and turn to Christ in faith.
“God is now declaring to everyone everywhere that they must repent . . . ” Acts 17:30)
Therefore having overlooked the times of ignorance, God is now declaring to men that all people everywhere should repent, 31 because He has fixed a day in which He will judge the world in righteousness through a Man whom He has appointed, having furnished proof to all men by raising Him from the dead.” (Acts 17:30-31)
God’s justice and holiness and wrath against sin is the reason why He calls for repentance from us. We are to preach repentance from sin and faith in Christ alone for salvation from sin. (Mark 1:15)
Israel was commanded to tell the nations about the true God and His glory:
“Tell of His glory among the nations,
His wonderful deeds among all the peoples” (Psalm 96:3)
The New Testament also shows us that our preaching ultimately involves communicating the glory of God, and the glory of Jesus Christ, who is God the eternal Son. As John Piper has written an entire book on this, that God is the gospel, ultimately, because it is about His perfect and holy character.
“And even if our gospel is veiled, it is veiled to those who are perishing, 4 in whose case the god of this world has blinded the minds of the unbelieving so that they might not see the light of the gospel of the glory of Christ, who is the image of God. 5 For we do not preach ourselves but Christ Jesus as Lord, and ourselves as your bond-servants for Jesus’ sake.6 For God, who said, “Light shall shine out of darkness,” is the One who has shone in our hearts to give the Light of the knowledge of the glory of God in the face of Christ.” (2 Corinthians 4:4-6)
Missions is the means or the way, of how God spreads His glory among all nations in history. When there is a group of redeemed people in a nation that is worshiping the true God, then God is fulfilling His goal of glorifying Himself among all the nations. (see Revelation 5:9; 7:9; 21:3)
