Here’s a great list of marriage tips that I found struck hard and are very meaningful.
1 – Be sure your spouse sees Jesus in you.
2 – Forgive always.To me, forgiveness has been achieved when I can replay an offensive event in my mind and not get angry or upset.Don’t make the mistake of thinking forgiveness is simply the ability to block out of your mind a painful event.
3 – Do not gossip to others about what your spouse has done to upset you. Take it to the throne room, not the ladies’ room.
4 – Fight pride daily. Pride expects of others what it’s unwilling to do itself. Like being the first to apologize; pride just hates that! 
5 – In marriage, there is an invisible altar called “self-sacrifice”. Climb upon it daily and your marriage will be the better for it.
6 – Remember submission is to be a mutual endeavor.
7 – Let go of lies you’ve believed about what a happy marriage is. The world sells us a bill of goods that simply doesn’t add up to the Word of God.
8 – To have peace in your home, remember you have to fight for it.
9 – Be aware that the marriage relationship is the natural manifestation here on earth of the love Christ has for His bride. When we keep that in mind, worrying about who left the cap off the toothpaste truly becomes a non-issue.
10 – Become cognizant of the fact that in the marriage relationship, God will use you both to make each other more like Him. He’s not just trying to change you, He’s trying to kill you! (To self!)
11 – Realize that by our human nature, none of want to be controlled by another. Coming under control to another is a work of the Spirit and we cannot force it in our marriages. If we are in control of our spouses, that means God is not. Watch out for this. Don’t mistake submission for control or power.
12 – Trust in the Lord with all your heart, and don’t rely on your own understanding. In all your ways acknowledge Him and He will direct your path.
