Ask the LORD in prayer in choosing the right partner for you. He may not be perfect but he will surely be the right fit for you. Being honest at the start of your relationship will help you to be more accepting and forgiving of each other. And putting JESUS at the center of your relationship will help you both in managing the challenges of your marriage. The LORD will always guide you, and will always help you deal with those changes you discover from your partner. Be willing to make some adjustments, and acknowledge that you have your own flaws too.
