This is a prayer that I found and say every night before bed. It fits our situation so perfectly; just thought I would share it.
O Lord, we long to have a child of our own. We are frustrated with all of the futile efforts we have made to fulfill this desire. We turn to You as our only hope because all life begins with You. We ask that You grant us the privilege of bringing a child into this world to rear and nurture in your admonition. Please remove every hindrance and obstacle to our conception.
We stand in faith that You will grant our petition just as You did when Hannah cried out to You for a child; nevertheless, if in Your infinite wisdom, You have looked into the future and, for whatever reason, determined it is not Your will for us to be the natural father and mother of a child, then we ask that You give us the grace to accept Your decision. Show us the next step to take. Help us exalt Your will above our own desires.
Give us peace as we submit to Your timing and Your sorvereign plan now. In the name of Jesus, I pray, Amen.
