Sometimes adopting can seem scary. What if this child is so broken that we can't possibly heal all the hurt in their lives? What if they have behavior issues? Or never live for God? The list goes on. See sometimes we think that's our job. The fixing, the healing...but it's God's. Our job is to act. To be willing to do something risky so that someone else, a stranger, can know and feel the love that God first showed us.
There are so many kids out there that don't know love. And if we don't go. If we don't say "No matter how hard this is, I am going to love that child" they never will. The scary parts are His. He can heal a broken heart. Psalm 147:23 says He heals the brokenhearted and binds up their wounds. But what if we won't do our part? What if we won't bring them into our homes, and give them that place to be restored?
If God is placing the idea of adoption on your heart, but the unknowns just seem like to much. You can't see how you can afford it, don't know if the child's needs will be more then you can handle, give it back to God. It belongs to him. He is more then able to work out the finances, mend that broken heart, and give you strength to do what he has called you for.
