Through the finished, redemptive work of Jesus Christ, the Father God provided everything that we need for Him to fulfill His plan in the earth through us and for us to live out our days on the earth in the abundance that Jesus came to provide (John 10:10). This includes healing for our bodies. Everything that God did for us is received by faith. Faith in God comes from hearing and hearing and hearing, what God says about it. Faith for salvation comes from hearing that Jesus provides a new birth for us. The exact same way, faith for healing in our bodies, comes from hearing what God did through Jesus to provide healing for us.
