God likes to do impossible things. Jesus born to a virgin. John born to Elizabeth when she was way too old for it to happen without supernatural intervention. Abraham’s son Isaac – same thing. I sometimes wonder why God does things this way.
But a Christmas pageant last week gave me a glimpse of one good, solid reason. When God works in human history, He works through people, and He needs at least some of us to be totally on board with what He’s doing, knowing without reservation that this thing is from God – being set in place by the Creator Himself.
Think about Mary. She knew without question that this birth was miraculous. Other people could question it, but nothing anyone could say would ever take away from her the reality of what she knew to be true. “Mary treasured up all these things and pondered them in her heart.” (Luke 2:19) She held onto this deep knowledge of God’s authorship, and in the coming years when things got very hard, it gave her the strength she needed to persevere, knowing that what God Himself has begun, He will be faithful to bring to completion.
