John 1:
1-2 Before anything else existed, there was Christ, with God. He has always been alive and is himself God. 3 He created everything there is—nothing exists that he didn’t make. 4 Eternal life is in him, and this life gives light to all mankind. 5 His life is the light that shines through the darkness—and the darkness can never extinguish it.   Living Bible

Success in marriage depends on the relationship that the husband and wife have with the Lord Jesus Christ. The scripture we just read tells us why.

Jesus Christ is God and without Him nothing was created that we can now see. Therefore, He was an active participant when God brought marriage into being in the Book of Genesis. Since then, we now know that there are many marriages that encounter problems.
Many marriages have areas of darkness. But the eternal life that is in Jesus Christ is the light that can shine through the dark areas of marriage if we will allow that.

Daniel 2:
22 God is the one who uncovers what lies deeply hidden;
he knows what hides in darkness;
light lives with him!   Common English Bible

The light that Jesus Christ shines into our dark areas is never dimmed or put out, except if we refuse to allow His light to shine there. If we refuse, then the dark areas remain and continue to cause problems in the marriage.
However, if we are willing to submit to Him and humble ourselves before Him and allow Him to change each of us from the inside, then His light will shine into our marriage and begin to make things right. Then our marriage will live up to the good success that God has in mind for every marriage, where the husband and wife together make Jesus Christ, the Lord of their marriage.

Jeremiah 29:
11 I know the plans that I have for you, declares the Lord. They are plans for peace and not disaster, plans to give you a future filled with hope.   God's Word Bible

This which God promises us applies to your marriage too. Here is how the Apostle Paul describes a Christian marriage.
Ephesians 5:
21 Honor Christ by submitting to each other.
22 You wives must submit to your husbands' leadership in the same way you submit to the Lord.
23 For a husband is in charge of his wife in the same way Christ is in charge of his body the Church. (He gave his very life to take care of it and be its Savior!)
24 So you wives must willingly obey your husbands in everything, just as the Church obeys Christ.
25 And you husbands, show the same kind of love to your wives as Christ showed to the Church when he died for her,
26 to make her holy and clean, washed by baptism and God’s Word;
27 so that he could give her to himself as a glorious Church without a single spot or wrinkle or any other blemish, being holy and without a single fault.
28 That is how husbands should treat their wives, loving them as parts of themselves. For since a man and his wife are now one, a man is really doing himself a favor and loving himself when he loves his wife!
29-30 No one hates his own body but lovingly cares for it, just as Christ cares for his body the Church, of which we are parts.
31 (That the husband and wife are one body is proved by the Scripture, which says, "A man must leave his father and mother when he marries so that he can be perfectly joined to his wife, and the two shall be one.")
32 I know this is hard to understand, but it is an illustration of the way we are parts of the body of Christ.
33 So again I say, a man must love his wife as a part of himself; and the wife must see to it that she deeply respects her husband—obeying, praising, and honoring him.   Living Bible

Father, today we come before You as husband and wife. We each submit ourselves willingly to You Lord Jesus Christ, and we declare that Your salvation is coming upon our marriage today.
We declare that as we continue to walk in Your light with You, Your healing process will continue in both of us.
We thank You with grateful hearts for this wonderful promise,    in Jesus' Mighty name,   Amen.

Hope we can get together again tomorrow,  God willing.
have a great day walking with The Lord Jesus Christ!
