A comforter for the bed, towels for the bathroom, a rug for the living room, each one serves a different purpose and function. But each one helps complete the house. Each one fills a function. So it is in life, in the church and especially in marriage.
For some faith will be your gift, the ability to just trust God and take Him at his word. Others will have the gift of service, like helping, cooking and cleaning will just come natural to you. Then there are some who are gifted teachers. Those who just have a way of explaining things so you can understand. Some are givers, they just seem to give, with a happy heart. Then there are some who just seem to show mercy, not matter how much they have been mistreated, etc.
Learn from others mistakes, and learn from others successes.
Seek God and your spiritual authorities, for wisdom!
