“’How will this be,’ Mary asked the angel, ’ sinceI am a virgin?…For nothing is impossible with God…‘I am the Lord’s servant,’ Mary answered. ‘May it be to me as you have said. Then the angel left her.’” Luke 1:34-38
Mary and Joseph didn’t understand how this could happen, that Mary, a virgin, could bear God’s Child. But even in the face of hard and unbelievable circumstances they trusted God’s Word, and acted in faithful obedience.
God doesn’t require complete understanding for you to be a Christian; just simple faith in the promises made to you in His Word. This faith in the promises of God fuels our obedience to Him.
