From my experience and studies I have found that when there is only 1 area that matters marriages work out.
The average marriage fails after 3 years in (2008) (80%) - After 3 years you have a 72% chance of divorcing. After 5 years of marriage you have a 25% chance of divorce. The percentage drops from here, but NEVER goes to 0. The divorce rate is 61% in the church and 45% out of the church - I think the reasons for so in "pedestals"
I know above stats are sad and depressing, but lets keep it real and honest.
Here are the things that are important. ( I honestly say ONLY)
1) That She be Christian (Fully walking the walk and Talking the talk)(The perfect, but walking what she believes.)
2) That She have the same "Calling" as you. I.e: If God has called you to be a Worship leader, the girl NEEDS to love worship and be able to worship with you. If you are called to be a Youth Pastor or Pastor, Missionary, or a pew sitter, that must be the commonality. The marriage body needs to work together not pull in two directions.
3) She needs to thirsty and hunger for the Word. Now, it's nice that she might always be reading, but lets be real, we all fall short in that area, BUT like the sin-nature, she must have conviction there to say, you know I NEED to read more, so I can grow more.
4) She needs to be able to pray with me. Marriage is a lot of Spiritual warfare. Satan is afraid is us doing GOD's work which defeats his kingdom, so imagine when to people are sold out, no compromise, on fire, recklessly abounded, to death for Jesus. Satan's a Punk and doesn't want that, so Pray is what will make your way through the rough times.
5) The desire to learn (not just the way of the bible, but the way of the world) It is unacceptable for a woman not to know the basics of life. (Changing a tire, Changing the oil, Simple plumbing, Finances, ) To a lot of you this ma sound like a lot, but its not, imagine the guy having to know how to learn, handle and react in emergencies to this very things, and A LOT MORE. Be my helper and actually help. Same goes with me and having kids, and house cleaning and cooking, I need to know, (already do) OR want to learn how to do what my girl can do. That way we can balance life out.
6) Strength and weakness is the final thing: Its important that if you are strong weak at prayer your partner needs to be Stronger, and if you are stronger at reading the Word, you need to the the strength for her weakness.
Here is my personal note: Girls DO NOT chose a man who is weaker than you spiritually. He is the spiritual leader NOT you. If you like someone and they are not strong enough in their walk. Dont date him and hope he gets stronger. Cause you might be really surprised when it gets worse or the guy even walks away from GOD.
