I saw the holy city, new Jerusalem, coming down out of heaven from God, prepared as a bride adorned for her husband. Revelation 21:2
There will be no marriage in heaven (Matt. 22:30), but we will still be male and female, because that is how God created us and it was good. The gift of marriage was given to point to something greater that God has in store for all who love Him.
Marriage, at its best, is a pointer to the joy that we will find in Jesus Christ and that Christ will find in His people in the new heaven and new earth. Even if you have an unhappy marriage, you have some sense of what marriage should be.
Christ is the bridegroom, and He brings His people into union with Himself. This shared life will be with God Himself, and the joy will go on increasing! The joys you experience in life remain in your memory so that you continue to derive happiness from them.
Jonathan Edwards says that it will be the same in eternity. Think about what that will be like when you have been in heaven for a million, million ages…. “Your knowledge will increase to eternity; and if your knowledge, your holiness; for as you increase in the knowledge of God, you will see more of his excellency (beauty), and the more you see of his excellency, the more you will love him, and the more you love God, the more delight and happiness you will have in him.”
All your experiences of joy in this life point to the ever-increasing joy that will be yours in Christ for all eternity. This is an “Amen!” moment.
