One of the best ways you can prepare to glorify God in marriage is to prepare to glorify God in singleness if you never do get married.
Ironically, the more content you are to serve God even if you never do get married, the more your heart is actually getting prepared to serve God when you do finally get married one day.
Generally speaking, the more willing you are to let something go, the more ready you are to receive it from God. The reason this is often the case is because God will never bless you with an idol. When God knows something is being elevated to a place greater than himself in your heart, God will often lovingly withhold this blessing until you repent of this sin and put this desire back in its rightful place.
Therefore, if you want to be married and please the Lord in marriage, also prepare your heart to serve the Lord in singleness. This helps you honor him before marriage and during marriage if the Lord does bless you with marriage one day.
