Luke 1: 37; For with God nothing shall be impossible.
The virgin birth is inexplicable except as a miracle. There is no possible way for a virgin to have a baby, but with God all things are possible. The Bible reveals, however, that there are some things that are impossible: (Heb. 6: 18;) it is impossible for God to lie; it is also impossible to please God without faith.
God’s Word becomes a self fulfilling prophecy when mixed with faith. The one word,"Come," from the lips of Jesus had enough power in it to enable Peter to walk on water, (Matt. 14: 29;) and also had the power to raise Lazarus from the dead. The word of the Lord that the angel Gabriel brought to Mary had the power to produce the virgin birth. When she believe it, her faith set God’s word into motion!
It doesn’t matter how impossible it may look. The Only question is, "Lord is this from You?" If so then the power it takes to accomplish the task is contained in the Word itself. Mix it with faith, and nothing that God has promised you is impossible!
