When people think of finding "the one" or Mr. or Mrs. Right they usually are thinking of finding someone that is compatible with them. And that should be a priority. Even the Bible asks, "Can two walk together, except they be agreed?" Amos 3:3 If you have ever had the misfortune of being paired up with someone who is not as grade conscious as you to work on a group project for school you probably noticed that sort of relationship doesn't go very well.
For a successful relationship one has to be matched with someone that shares the same values and priories as you do. It is unbiblical to marry unbelievers or blindly put up with abuse or wrong doing - even God doesn't do that. "...The Lord said, 'My Spirit shall not strive with man forever...'" (Genesis 6:3) But I want to point out that the reasons for finding Mr. or Mrs. Right go wrong because people are focused on someone else being right for them instead of becoming the right kind of people to be in a relationship with themselves.
If the main goal behind finding a partner is for someone else to meet your own "needs" (or wants) in a relationship instead of meeting theirs that is a problem and is why many relationships fail or are miserable at best. It is like a flea and a dog, or in some cases as one wife once said, like two fleas and no dog. Focusing on what you can get out of someone should never be the motive of marriage or any relationship.
After creation the Bible says, "Then the LORD God formed the man from the dust of the ground. He breathed the breath of life into the man's nostrils, and the man became a living person." Genesis 2:7 "So the LORD God caused a deep sleep to fall upon the man, and he slept; then He took one of his ribs and closed up the flesh at that place. The LORD God fashioned into a woman the rib which He had taken from the man, and brought her to the man. The man said, 'This is now bone of my bones, and flesh of my flesh; she shall be called Woman, because she was taken out of Man.' For this reason a man shall leave his father and his mother, and be joined to his wife; and they shall become one flesh." Genesis 2:21-24
There are many important points in this passage that we would do well to learn from. First of all, Adam did not do his own searching for Mrs. Right. He rested in God, patiently waiting on the Lord to give him a partner in His timing and allowed God to pick a mate for him. And when God did Adam accepted God's choice for him without alterations.
Next we note that God formed Eve directly from Adam. God could have easily formed another person from the dust of the ground, but by creating her directly from Adam we can see the equality God intended between husband and wife, man and woman. No one could say the dust God made me from is better, more important, or somehow superior to the dust God used to make someone else. We are a part of each other and should treat each other as such.
It is also worth noting from the Bible text above that a man should leave is father and mother and be joined to his wife. So if you are still living with or are dependent on your parents and can't support or take care of yourself, it seems safe to say that, you have no business seeking Mr. or Mrs. Right right now. Therefore, if you are a young person, teen, or child, or your circumstances just aren't ideal for starting a family, prayerfully consider putting dating off. But however old you are, remember you should always wait on God to form a match for you.
