Dear friend, please don't worry. There is a time for everything, and God's timing is always the best. Even though you've just turned 20 and are concerned about marriage, it's important to remember that everything happens in its own time. I understand that it may feel like it's taking a long time, but it's important to be patient and have faith in God's plan. He has the best plan for you, and everything will fall into place at the right time.
