John Bunyan was an uneducated tinker. His dad worked with brass, took John out of basic kindergarten, and then put him to work. John Bunyan would serve in the military where he would call himself, "The chiefest of sinners" and go on and write a book called Grace Abounding to the Chiefest of Sinners. His Pilgrims Progress outsold all other book save the Bible.
What made the difference? What made the turnaround? It was this simple thought by Martin Luther... Paul taught justification by faith in Christ Jesus, without the deeds of the Law. He reported this to the disciples at Antioch. Among the disciples were some that had been brought up in the ancient customs of the Jews. These rose against Paul in quick indignation, accusing him of propagating a gospel of lawlessness. Great dissension followed. Paul and Barnabas stood up for the truth. They testified: "Wherever we preached to the Gentiles, the Holy Ghost came upon those who received the Word. This happened everywhere. We preached not circumcision, we did not require observance of the Law. We preached faith in Jesus Christ. At our preaching of faith, God gave to the hearers the Holy Ghost." From this fact Paul and Barnabas inferred that the Holy Ghost approved the faith of the Gentiles without the Law and circumcision. If the faith of the Gentiles had not pleased the Holy Ghost, He would not have manifested His presence in the uncircumcised hearers of the Word. -

Especially... "Wherever we preached to the Gentiles, the Holy Ghost came upon those who received the Word." And what was that simple little thought? "Paul taught justification by faith in Christ Jesus, without the deeds of the Law."
In studying Paul he would not even Baptize... "I thank God that I baptized none of you, but Crispus and Gaius;" - 1 Corinthians 1:14... and his main focus was... For I determined not to know any thing among you, save Jesus Christ, and him crucified. - 1 Corinthians 2:2
So.... Simple faith in Christ will do! Whatever it is! Healing, Salvation, the Holy Ghost... Simple faith in Christ will do!
Question... I did not speak in tongues?
Answer... Have all the gifts of healing? do all speak with tongues? do all interpret? - 1 Corinthians 12:30
Simple faith in Christ is enough! Simple faith in Christ will do! Are you still broken? Well... In the hallmark of faith... Out of weakness were made strong. - Hebrews 11:34
We will believe in the possibilities of being strong... Especially when we are weak and broken.
