LUKE 1:26-38
Everything about Jesus' birth was natural and normal except that a man didn't provide the seed; it came from the Holy Spirit. God's Word is called the incorruptible seed,1 Peter 1:23.
Gabriel took the Word of God that had been spoken through prophecy about the Messiah, bringing it to Mary. Then the Holy Spirit moved over her like He did over the waters of the earth in Genesis 1:2. And the Word was made flesh, John 1:14.
Ever miracle we experience is similar because we must receive God's Words into our hearts and take care of it for a while by meditating on it, before it can come to pass.
Mary is the only person that has ever had a baby that was produced by the Word of God and it took God's supernatural seed to do so.
We must receive and believe God's Word in our heart in order to give birth to our dreams in reality!
