He Lives Within You - Max Lucado

The virgin birth is more, much more, than a Christmas story; it is a picture of how close Christ will come to you. The first stop on his itinerary was a womb. Where will God go to touch the world? Look deep within Mary for an answer.

Better still, look deep within yourself. What he did with Mary, he offers to us! He issues a Mary-level invitation to all his children. "If you'll let me, I'll move in!"
Proliferating throughout the scriptures is a preposition that leaves no doubt- the preposition in. Jesus lives in his children.

John was clear, "Those who obey his commands live in him, and he in them" (I John 3:24 NIV, emphasis mine). Christ grew in Mary until he had to come out. Christ will grow in you until the same occurs. He will come out in your speech, in your actions, in your decisions. Every place you live will be a Bethlehem, and every day you live will be a Christmas. You, like Mary, will deliver Christ into the world.

God in us! Have we sounded the depth of this promise? God was with Adam and Eve. God was with Abraham. God was with Moses and the children of Israel. God was with the apostles. But he is in you. You are a modern-day Mary. Even more so. He was a fetus in her, but he is a force in you. He will do what you cannot.

Can't stop drinking? Christ can. And he lives within you.
Can't stop worrying? Christ can. And he lives within you.
Can't forgive the jerk, forget the past, or forsake your bad habits? Christ can! And he lives within you.
