True sonship is being free from dependence on man for support and assurance. Jesus knew the hearts of men, that they were flawed and ultimately an unreliable source of security. So, Jesus demonstrated true relationship with God by depending solely on the guidance of support of the Father. Jesus from absorbed in His intimacy with the Father, and that's all that He ever needed. He didn't need a human support group, and He was never offended by the abandonment or betrayal of people. Why? Because His contentment was never committed into the hands of fallible people.
This is the foundation of all faith, peace, and joy.
In addition, introduced in this sermon are basic principles of healing ministry...healing was paid for on the cross and therefore, we are ministers of healing just as we are preachers of the cross and resurrection of Christ. It is always God's will to heal the sick, just as it is always His will to save the lost; as, both were paid for in the moment of Christ's crucifixion.
