We’re out there to love people. We can’t carry the heavy burden of what if. If we love the person and we believe that Jesus came to bear the heaviness and weight of the punishment of sin, you will see people healed.
You’ll never live by faith if you hold to the “yes and no” gospel. “I don’t know what God’s will is. If He doesn’t heal them, I’ll go back and reconcile my thinking.” No! It’s “Yes and Amen!” through Him. God is saying YES.
