Jesus came to preach the gospel of an earthly kingdom, that born again believers might be able to experience righteousness, joy and peace here on earth.

Thy kingdom come. Thy will be done in earth, as it is in heaven.
Matthew 6:10

Once you have obtained a true assurance of salvation, once you have experienced the joy of a right relationship with the Master and the gifts of the Holy Spirit, simply being saved is not enough. You must allow His grace to operate in your life and prepare you for service to others (John 15:13) .

Salvation changes your position in Christ, but practically speaking you are still a sinner. For every true believer, there must be a change in the pattern of sin. Sanctification is a process in which He calls you to become conformed to the image of His Son (Ephesians 4:11-13), and it is also the means by which Christ will establish His earthly kingdom.

And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea. And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband. And I heard a great voice out of heaven saying, Behold, the tabernacle of God is with men, and he will dwell with them, and they shall be his people, and God himself shall be with them, and be their God. And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away.
Revelation 21:1-4

And it shall come to pass in the last days, that the mountain of the Lord's house shall be established in the top of the mountains, and shall be exalted above the hills; and all nations shall flow unto it. And many people shall go and say, Come ye, and let us go up to the mountain of the Lord, to the house of the God of Jacob; and he will teach us of his ways, and we will walk in his paths: for out of Zion shall go forth the law, and the word of the Lord from Jerusalem. And he shall judge among the nations, and shall rebuke many people: and they shall beat their swords into plowshares, and their spears into pruninghooks: nation shall not lift up sword against nation, neither shall they learn war any more. O house of Jacob, come ye, and let us walk in the light of the Lord.
Isaiah 2:1-5

Jesus came to preach the gospel of the kingdom (Mark 1:14; Matthew 6:11; Matthew 10:4-6). The gospel contains the message of salvation, but it does not end there. Every new believer, having been justified by God's grace through the atonement of Christ, is then called to be sanctified by His Spirit and prepare himself for active service to others (Romans 12:1-2).

Great is the Lord, and greatly to be praised in the city of our God, in the mountain of his holiness. Beautiful for situation, the joy of the whole earth, is mount Zion, on the sides of the north, the city of the great King.
Psalm 48:1-2

For the Lord hath chosen Zion; he hath desired it for his habitation. This is my rest for ever: here will I dwell; for I have desired it. I will abundantly bless her provision: I will satisfy her poor with bread. I will also clothe her priests with salvation: and her saints shall shout aloud for joy.
Psalm 132:13-16

We live in a marvelous age in which God will soon fulfill many of the prophecies that were made by His servants in times past. Zion, His kingdom, will soon be established in a very tangible way here upon the earth. And there will be no more tears, nor crying, nor pain, nor sorrow. All of these things will pass away. Christ said the kingdom was at hand. That is because this joyous condition is available to those of His people who will join together in submission to His will.

The answer is not found in starting another evangelical church. Listen to His voice. Allow His Spirit to guide you and His grace to sustain you. The kingdom of God is available to those who will obey His will for their lives. Give your heart to Him in full submission to His will. The kingdom is at hand; it is available to you.
