Luke 1:38,45 Mary responded, "I am the Lord’s servant, and I am willing to accept whatever he wants. May everything you have said come true." And then the angel left her. "You are blessed, because you believed that the Lord would do what he said."
Mary was a young teenage girl engaged to be married. She was a very devout young woman and the Lord was very pleased with her. He sent Gabriel to her to inform her that she was going to be carrying Christ in her womb. She was taken aback with this news at first, but then yielded to what the angel had said. She was willing to be the vessel in which God would become man.
I am sure that Mary did not fully understand all that this would mean for her. She wasn't yet married and there surely would be gossipers to deal with. She didn't know how Joseph or her parents would act. She didn't know what she would have to do differently to raise the Christ-child. She didn't know if she would have to make drastic changes in her life as the child grew; after all, He would be God in the flesh.
Yet, Mary knew that whatever was going to happen everything would work out because this was of God and He was in control. She believed the message and trusted God in what He was about to do. As a result, she was blessed by God. I am sure that in spite of all the uncertainties that lied ahead, she had an overwhelming peace in her soul. She put it all in the Lord's hands.
Just like Mary, we need to just put the uncertainties ahead of us in the Lord's hands. We have to believe and trust in what the Lord leads us to do. We will never face the future alone when we rest in Him. God will bless you with peace and joy as you learn to lean on Jesus every moment of every day.
