Is Marriage Necessary?

Tonight at work, my manager and I sat and talked for about half an hour (We had worked and talked for about an hour before) about the question of whether or not a marriage relationship was necessary to be spiritually complete, as far as, you cannot feel as though nothing is missing in your life unless you have a spouse. The basic fact that all Christians must accept is that God created man and woman to enter into a marriage relationship, which is sacred and holy, and between only them. God created us to need the intimacy, not just sexual, but emotional and spiritual, that comes with marriage. Is marriage necessary for completion? Depends on who you ask. My manager believes that some people have a spiritual gift from God to work past being single and achieve spiritual completion for God, but the default for all humans is to need a spouse.
Now is a spouse all that one needs? No, of course not. You need a satisfying career, satisfying friends, and a satisfying relationship with God, among other things, to feel complete. But God created in us a desire and a need to be intimate with someone - to connect our souls with someone else in a way that only comes through marriage. You can be intimate with a close friend, but nothing comes close to the intimacy of sharing your life with someone. God created us with a desire to have community with people, and especially with just one. However, the intimacy with your spouse will never override the need for intimacy with God.
Do we need to share our lives with another person? Personally, I don't need to. Do I want to? Heck yes I do! I want to get married, have kids, and enjoy the sacred joy that comes through marriage. Is it necessary for me to live my life to the fullest? No, it isn't. I could go through life and enjoy it and be single my whole life. But I, along with every other person on this planet, need intimacy with my friends, desire intimacy with my wife, and require intimacy with God.
We have a need for intimacy, God has a need for it too. Why did God create people? He knew we would sin, he knew we would break his heart by requiring him to damn billions of us to Hell; so why would he do it? I believe God created humans because he had a need for intimacy with us. He had a need to have community and intimacy with us. Was God incomplete before he created us? By all means, no, he was totally complete - he's the essence of completion. But he desired intimacy with us. He desired with all his heart to have us share our lives with him.
So is intimacy required for living a complete life? Yes. Is a spouse required? I believe not, but you must realize that if you don't have a spouse, you will have to find that missing intimacy in both your close friends and more so in God. Don't fool yourself into thinking that a spouse is the key to completion - that only comes in God. A spouse is the sprinkles on the cake. Is a cake complete without sprinkles? Yes. Is it more enjoyable with them? Yes it is.
