[7] Let us rejoice and be glad and give the glory to Him, for the marriage of the Lamb has come and His bride has made herself ready.”

There are at least two aspects related to the readiness of the bride. One involves the composition or makeup of the bride. What does scripture say about this? The other involves our relationship to God and to one another.

Our relationship I believe is seen in the call for a separation from the world as it is seen by God. But, this separation is also a call for purification, and unification. Separate from the world and unto the Lord. But isn’t this who we are in Christ? Yes — Spiritually speaking, in Christ, this is who we are, but we will also be there physically before the Lord returns.
25 For whoever wishes to save his life will lose it; but whoever loses his life for My sake will find it. 26 For what will it profit a man if he gains the whole world and forfeits his soul? Or what will a man give in exchange for his soul?
Matthew 16:25-26
Jesus in this passage is speaking to both the physical and the Spiritual kingdom. The Spiritual already exists, the physical is yet to come. “Thy kingdom come, Thy will be done on earth as it is in heaven”.

God’s final call to His people in the Tribulation is to come out of Babylon (the world). We see this acted out today in pockets where the world is so opposed to God, that when one turns to Him their very life is on the line and total commitment is made. There will be a bride who is totally committed unto the death during the Tribulation. This commitment will yield up the final Spiritual composition of the bride. Jew and Gentile — one new man. This unity will bring a positive answer to our Lord’s Prayer for unity in John 17.

The one new man is the very reason that Jesus was presented in the Scriptures as the Savior, The Messiah. Israel was told of the coming Savior in Isaiah 53. Hear we have the picture of Jesus as savior. But it’s in Isaiah 54 that we are given a look at the future of Israel as she relates to the Bride or marriage of Christ. The Savior, The Redeemer.

First Isaiah 54 depicts a land devoid of bearing children for her future kingdom, because of her condition following the preceding chapter 53 crucifixion of her Messiah. This we are told results in her widowhood. Her husband the word of God has been sacrificed and rejected by her.

But she will not be forsaken, in fact even though she is barren, children are being produced for her. How can that be? Think about it. Though cast away and cut off, we were grafted in in her place. And in this passage she is promised to once again be remarried to he redeemer. Listen:
Fear not, for you will not be put to shame; And do not feel humiliated, for you will not be disgraced; But you will forget the shame of your youth, And the reproach of your widowhood you will remember no more. “For your husband is your Maker, Whose name is the Lord of hosts; And your Redeemer is the Holy One of Israel, Who is called the God of all the earth.
Isaiah 54:4-5

Jesus her husband and her maker has become her redeemer. And her tents must be enlarged (see verses 1-3), why would that be necessary? Think again — why? Because of us. We have been joined to them as “one new man”.
because God had provided something better for us, so that apart from us they would not be made perfect.
Hebrews 11:40.

Have you ever wondered why we are called the Bride of Christ? Christ our equivalent to Israel’s Messiah.

You yourselves are my witnesses that I said, ‘ I am not the Christ,’ but, ‘I have been sent ahead of Him.’ He who has the bride is the bridegroom (John 3:28-29a). In this passage the bride that Jesus is beginning to form is from the Jews. The bride includes Jews first and interestingly they will also be the last to be saved and added to the bride. When Israel is finally saved our bridegroom will return.
