Is Jesus Christ coming again?
Yes. The Lord Jesus Christ shall appear, and He is coming. Until the Prince of Peace comes, there will be no peace on earth; Jerusalem will have no peace until He is back in Jerusalem. When He comes, God's children shall be like Him, for they shall see Him as He is.
Les teaches from verse 2 that “when He shall appear” means He is going to appear; the Lord Jesus Christ is coming. He notes the world may think it can keep going forever and that the United Nations will solve all the world’s problems, but there will be no peace on earth until the Prince of Peace comes. Praying for the peace of Jerusalem is therefore praying for the Lord’s coming, because Jerusalem will have no peace until the Prince of Peace is back in Jerusalem. This one thing we know: when He comes, and He is coming, we shall be like Him, for we shall see Him as He is.
Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is.
