Because of Adam’s transgression, all men were constituted sinners (Rom. 5:19), man was put out of the Garden of Eden, and the way to the tree of life (a picture of Christ as the real life) was closed (Gen. 3:22-24). In the New Testament Jesus Christ came to resolve this problem. He took away sin (John 1:29); cast out Satan, the source of sin (John 12:31); and was lifted up to save us from the satanic nature (John 3:14).
Although we were constituted sinners in Adam, we were constituted righteous in Christ (Rom. 5:19). Based on this righteousness, we receive eternal life (5:18) and are born again.
The later part of John 3 speaks of the bride as the increase of Jesus Christ (v. 29-30). This bride is composed of all who have been healed from the satanic nature, become righteous in Christ, and received eternal life. Regeneration not only brings the divine life into the believers and annuls the satanic nature in their flesh, but it also makes them the corporate bride for Christ’s increase.*
John the baptist said, “He who has the bride is the bridegroom” (John 3:29). This statement, although seemingly generic, has a context clearly about Jesus Christ. New Jerusalem is the fulfillment of this statement. Revelation 19:7 says, “Let us rejoice and exult, and let us give the glory to Him, for the marriage of the Lamb has come, and His wife has made herself ready.” Jesus Christ is the Lamb and New Jerusalem, the composition of all regenerated people, is His bride.
In Revelation 21:2 John the apostle saw New Jerusalem as “a bride adorned for her husband,” the eternal outcome of John 3.
