Paul and Barnabas were preaching the gospel in Lystra, and while Paul was preaching, a man sat listening to him who was crippled from birth and had never walked. (Acts 14:8) As the man listened, Paul must have observed the man’s body language and watched how he was responding to his sermon.
I imagine that Paul would have been speaking about the resurrection power of Jesus Christ, which is able to raise the dead, heal the sick and cause the lame to walk again. There must have been an excitement and an anticipation of faith on this man’s face that caused Paul to see that the man had the faith to be made well. And acting upon the man’s faith, (not Paul or Barnabas’s faith), Paul commanded the man to stand up on his feet. The scripture didn’t say that the man stood up slowly and needed help to get to his feet. This man “sprang up and began walking.”
This miracle was according to the measure of this man’s faith. “each according to the measure of faith that God has assigned.” (Romans 12:3) We know that without faith it is impossible to please God, “for whoever would draw near to God must believe that he exists and that he rewards those who seek him.” (Hebrews 11:6)
Jesus often healed people and commented on their faith making them whole. And for those who struggled to believe, there was help for their unbelief. (Mark 9:23-27) Faith is required for miracles, healing and deliverance to take place. In Mark 9, the father prayed against unbelief in order to increase his measure of faith to receive healing for his son. Faith increases through prayer, hearing the word and also in Mark 9, Jesus encouraged his disciples to fast and pray. Increase your faith and believe God for healing.
