Not only are we lost in sin, but the earth is defiled. 
Isaiah lamented, “The earth mourneth and fadeth away, the world languisheth and fadeth away, the haughty people of the earth do languish.  The earth also is defiled under the inhabitants thereof” (Is 24:4-5).

All creation groans in bondage and yearns for deliverance. 
Paul said, “For we know that the whole creation groaneth and travaileth in pain together until now.” (Rom 8:22). 

Jesus brought light to the entire world. 
Isaiah predicted, “Arise, shine; for thy light is come, and the glory of the Lord is risen upon thee.  For, behold, the darkness shall cover the earth, and gross darkness the people: but the Lord shall arise upon thee, and his glory shall be seen upon thee” (Is 60:2). Jesus said that he is that light: “I am the light of the world” (John 8:12). 

God will fill the earth with his glory. 
He promised Moses, “All the earth shall be filled with the glory of the Lord” (Nu 14:21).  The Bible prophesies, “For the earth shall be filled with the knowledge of the glory of the Lord, as the waters cover the sea” (Hab 2:14).

Jesus also came to establish his kingdom. 
Isaiah had foretold, “Of the increase of his government and peace there shall be no end, upon the throne of David, and upon his kingdom, to order it, and to establish it with judgment and with justice from henceforth even for ever” (Is 9:7).

Jesus built his church and placed the keys of the kingdom in it. 
He told Peter, “Upon this rock I will build my church; and the gates of hell shall not prevail against it.  And I will give unto thee the keys of the kingdom of heaven” (Mat 16:18-19).

Jesus sent his apostles to preach the gospel and build up his kingdom. 
“And he sent them to preach the kingdom of God, and to heal the sick” (Luke 9:2).

The preaching of the gospel heals us from sin’s ills. 
The Bible records that the apostles “departed, and went through the towns, preaching the gospel, and healing every where” (Luke 9:6).

People lost in sin’s darkness are delivered by the gospel into God’s kingdom. 
Paul praised God, “Who hath delivered us from the power of darkness, and hath translated us into the kingdom of his dear Son” (Col 1:13).

The Bible says that those who obey the gospel become a holy nation. 
Peter addressed the church, “But ye are a chosen generation, a royal priesthood, an holy nation, . . .which in time past were not a people, but are now the people of God” (1 P 2:9-10).

The gospel delivers us as well as creation from darkness. 
Paul wrote, “By him all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him. . .  And, having made peace through the blood of his cross, by him to reconcile all things unto himself” (Col 1:20).

Jesus reconciles all the world to God.  Paul said,
“God was in Christ, reconciling the world unto himself” (2 Cor 5:19).

All creation waits for the holy kingdom. 
Paul wrote, “For the earnest expectation of the creature waiteth for the manifestation of the sons of God. . .  Because the creature itself also shall be delivered from the bondage of corruption into the glorious liberty of the children of God” (Rom 8:19, 21).

Bringing people into God’s kingdom reconciles the world to God. 
Paul explained, Christ “hath given to us the ministry of reconciliation; . . . and hath committed unto us the word of reconciliation” (2 Cor 5:18-19).

The Bible promises that the kingdoms of this world will become the kingdom of God. 
John foresaw when “The kingdoms of this world are become the kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever” (Rev 11:15).

Christians work with Jesus to bring His kingdom on earth. 
The Bible records, “They delivered them the decrees for to keep, that were ordained of the apostles and elders which were at Jerusalem.  And so were the churches established in the faith, and increased in number daily” (Acts 16:4-5).
