Acts 14:5-10 ESV When an attempt was made by both Gentiles and Jews, with their rulers, to mistreat them and to stone them, (6) they learned of it and fled to Lystra and Derbe, cities of Lycaonia, and to the surrounding country, (7) and there they continued to preach the gospel. (8) Now at Lystra there was a man sitting who could not use his feet. He was crippled from birth and had never walked. (9) He listened to Paul speaking. And Paul, looking intently at him and seeing that he had faith to be made well, (10) said in a loud voice, "Stand upright on your feet." And he sprang up and began walking.
Paul and Barnabas were on their first Apostolic journey. Look at verse 7. “And there they preached the gospel.” As Paul preached the gospel message we can see the results in verse 9. “The same heard Paul speak: who stedfastly beholding him, and perceiving that he had faith to be healed,” Was the man healed by verse 9? No! It is not faith plus works, but a faith that works:
James 2:14 ESV What good is it, my brothers, if someone says he has faith but does not have works? Can that faith save him?
James 2:17-19 ESV So also faith by itself, if it does not have works, is dead. (18) But someone will say, "You have faith and I have works." Show me your faith apart from your works, and I will show you my faith by my works. (19) You believe that God is one; you do well. Even the demons believe—and shudder!
James 1:22 ESV But be doers of the word, and not hearers only, deceiving yourselves.
