The birth of Isaac is the fulfillment of God's promise to Abraham. But it was, of course, impossible in human terms.
Sarah was well past the child bearing years -- so far past that when she heard the promise, she laughed at its impossibility. And she devised the scheme to have Hagar bear a son to Abraham.
But the Lord opened her womb to bear Isaac. That had been His plan all along.
How often do we dismiss our dreams and the desires of our hearts because they seem improbable or even impossible. If God puts the desire in your heart, He will make a way for it to come to fruition.
But we can't just sit back and do nothing. That is not to say that we should interfere in God's plan the way Sarah did. It does mean that we need to prepare ourselves to be the instrument that God desires.
If He puts it into your heart to write, you can't just sit back and wait for inspiration to hit. You need to sit at the keyboard or the yellow pad and put words on paper or screen. The more you practice putting words together well, the better prepared you will be to disseminate the information He wants you to share.
Sarah would have served better had she simply begun making clothes for the baby God was going to send.
Help us to see the benefit of readiness and lead us into preparedness for Your plans. Keep us from the sin of running out ahead of You when we should be waiting and following.
In Jesus' most precious name,
