Isaiah 62:6 says, I have set watchmen upon thy walls, O Jerusalem, which shall never hold their peace day nor night: ye that make mention of the Lord, keep not silence, God said He had set a watchman on the wall. This refers to preachers, but I believe it also refers to all Christians. We are to be ever alert to the threat of evil and we should never stay quiet when we see evil in the world. God has given us the responsibility of being alert for evil and crying out when we see it, and this is not just the responsibility of preachers.
Verse seven adds, And give him no rest, till he establish, and till he make Jerusalem a praise in the earth. Isaiah said this watchman would have no rest until God was established and until He made Jerusalem the praise of the earth. This will happen when Jesus Christ returns to claim His church, and until then we must continue to reach out to the lost world with the gospel
Verse eight continues, The Lord hath sworn by his right hand, and by the arm of his strength, Surely I will no more give thy corn to be meat for thine enemies; and the sons of the stranger shall not drink thy wine, for the which thou hast laboured: Isaiah said God made a promise that the people of Israel would be protected by His strong right arm and would not be enslaved again. I believe this means spiritually, and once we accept Jesus Christ as our personal Savior and Lord, we are secured by His power and will never be under the death sentence of sin again.
Verse nine concludes, But they that have gathered it shall eat it, and praise the Lord; and they that have brought it together shall drink it in the courts of my holiness. Isaiah added that no one else would eat the fruits of their labor. The fruits of our labor as Christians should be the spreading of the gospel, and if we accept God’s gift of salvation, no one else will be able to take it away from us.
Verse ten states, Go through, go through the gates; prepare ye the way of the people; cast up, cast up the highway; gather out the stones; lift up a standard for the people. This passage refers to the Jews being delivered from Babylon and rebuilding Jerusalem and other cities, but in the broader context, it applies to Jesus Christ coming to deliver those who put their faith in Him when He first came and to our continuing to put our faith in Him until He returns. Isaiah said that the people of Israel were to proclaim God’s word everywhere. They were to go through His gates and lift up His standard. Jesus Christ is the only gate that we can go through to be restored to a right relationship with God, and He is the standard that we should lift up. We are also to proclaim this as we call on people to prepare the way for the return of Jesus Christ.
Verse eleven adds, Behold, the Lord hath proclaimed unto the end of the world, Say ye to the daughter of Zion, Behold, thy salvation cometh; behold, his reward is with him, and his work before him. The people of Israel were promised that salvation was coming. They would need to put their faith in this coming Messiah and He would bring their reward, which was everlasting life with God in heaven. Jesus Christ is the only One Who can bring us salvation.
Verse twelve continues, And they shall call them, The holy people, The redeemed of the Lord: and thou shalt be called, Sought out, A city not forsaken. Isaiah said once the people of Israel began to live by faith in God and the coming Messiah that they would be called a holy people and others would seek them out to learn how to become a part of God’s kingdom as well. We, as followers of Jesus Christ are a holy people, or set aside from the world by our faith in Jesus Christ. It would be nice if people sought us out to hear the gospel, but too often, we have a hard time getting people to accept Jesus Christ as their Savior and Lord when we seek them out. Still, we should never stop trying to reach them.
