I received these questions and thought I'd just blog my answers.
What should be a single Christian's motive/s for wanting to be married?
There are many different motives for wanting to be married, but I believe you must sift your heart's motives through God's filter. What is the purpose of marriage in the bible? I believe there are two main reasons: procreation and to mirror the relationship of Christ and the church to an unbelieving world.
I also firmly believe that God can place the desire to be married on a person's heart. There was a season in my life where I really didn't long for marriage (it was short, but there was a time)!
After awhile God started stirring in me a desire to get married. I knew my motives were pure. I knew my longing for marriage was from God because I truly wanted it to a) it would point people to Him and b) if being married I could become more Christlike.
Say you're single, of marriagable age & maturity, but with no "prospect" on the horizon. What should be our reason for wanting to be married? Is it for loneliness, or self-esteem (emotional neediness), or even purely physical?
All three of those reasons are reasons people long for marriage. However we must look to God to satisfy all our need first. A mate will never be an all in all. We must be careful to not make marriage an idol.
What is it that stops these motions driving us to desperation? If the Lord is our source of contentment (and, as many books have said, our husband, prince, etc) then why would we still desire to be with someone?
Psalms 37:4 states: Delight yourself in the LORD and he will give you the desires of your heart.
In the greek the word: give, has two means: 1) to place 2) to bestow
I believe God can place the desire to be married on your heart and then bestow that to you in His perfect timing. We must examine our heart to know if our motives are selfish or from God.
And, is it right to pray for God to send you a husband/wife? Again, what would be one's motive in this?
New Year's Eve 1995 God convicted me to not pray for a husband, but to pray for MY husband. So I did! Each year I had a certian prayer request that would come to my heart and I'd faithfully pray for him! I knew praying for a husband was coming from a selfish place in my heart.
Hope this helped!
