It really doesn't have to be all that hard but there are those that have a fear of rejection or commitment and make things more complicated than they really are. The fact is, while it is wise to pray to God for Him to search and find a spouse of your heart's desire He is not going to simply drop a prospective spouse in your lap. This requires action and you must be ready to act when this opportunity should happen to arise.
of course you need to introduce yourself to a girl, make friends with her, cheer her up, help her and date her in order to be her lover and later marry her.
It also does not mean God will provide is what you gonna do is to sleep and when you're awake then a bundle of cash will suddenly appear to you.
it is really trial and error. it takes time to know a man's character.
like the Chinese are saying "The distance tests the horse's strength so time reveals a person's character"
The golden rule in finding a good partner is make sure that he is not lazy, not an angry/furious man and lover of Biblical teachings.
