How is it possible that rebellious hearts that are opposed to God, predisposed to reject God and his word, hardened so as to not submit to his authority, how is it possible that spiritual life might spring forth in the form of a soft heart that believes and obeys God?  The line that the angel told Mary is the same line that he tells each of us in response to this question, “Nothing is impossible with God.”  Nothing is impossible with God. 

How might we be convinced of the truth of God’s word?  How might we have faith that these words are the very words of God?  If you have opened God’s word and read it, if you have heard it read and preached to you, and you have believed it, if you have received it with faith as the very word of God delivered to you, concerning God’s character and your sin and His means of redeeming you through Jesus Christ, then you have had a supernatural experience.  The Holy Spirit has given you spiritual eyes of faith.  It is impossible with man to conceive of this reality.  It is impossible for man on his own to have faith.  It is impossible for man to be born again.  It is impossible to please God on your own.  It’s easier for a camel to go through the eye of a needle than for a man to earn his way into heaven.  But what is impossible with man is possible with God. 

Hebrews 1:2-4 “In these last days he has spoken to us by his Son, whom he appointed the heir of all things, through whom also he created the world.  He is the radiance of the glory of God and the exact imprint of his nature, and he upholds the universe by the word of his power. After making purification for sins, he sat down at the right hand of the Majesty on high, having become as much superior to angels as the name he has inherited is more excellent than theirs.”

You and I probably won’t see any angels spontaneously appearing by our night stands giving us confirmation that God has spoken to us.  That’s ok, because we’ve got something better.  God himself put on flesh, and this is why we know with absolute confidence that God has spoken to us.  And if you believe this, then God’s Spirit has rested in your heart to give you this faith.  And with this certainty we echo Mary’s words, “Behold, I am the servant of the Lord; let it be to me according to your word.”
