There are those were sent and there those who went and those who were sent will be seen by the works. Acts 13:2 As they ministered to the Lord and fasted, the Holy Spirit said, “Now separate to Me Barnabas and Saul for the work to which I have called them.”
The ministry of Christ is not an idle ministry. Wherever the Holy Spirit is present, there is healing, deliverance, signs and wonders. The teaching is followed by practicals. Wherever Jesus went, people were astonished and dropped everything to follow Him. The proconsul heard about Paul’s ministry but when he witnesses the works of the Holy Spirit, he was astonished. Acts 13:12 Then the proconsul believed, when he saw what had been done, being astonished at the teaching of the Lord.
Christians knows the bible what they need is the works. Naaman knew God is there but nothing connected to what he heard until the encounter. 2 Kings 5:15 Then Naaman and his entire party went back to find the man of God. They stood before him, and Naaman said, “Now I know that there is no God in all the world except in Israel. So please accept a gift from your servant.”
James 2:19-20 You believe that there is one God. You do well. Even the demons believe-and tremble! But do you want to know, O foolish man, that faith without works is dead?
