Jesus had said thy son liveth, this man exercised a trusting faith. He was saved right then and there. The historical faith is seen in one s believing that God exists. The intellectual faith is seen in believing that God will reward them who diligently seek Him. But a person can believe that God exists and that God will save him if he diligently seeks Him and still not come to Him for salvation.
True salvation requires three kinds of faith.
Verse 13 declares that whosoever shall call upon the name of the Lord shall be saved. Verse 14 then explains that a person will not call on God until he believes in God s existence and that God will answer his call. My own personal testimony confirms the necessity of three kinds of faith for salvation. I have always believed in the existence of God. I have always believed what the Bible says about Jesus Christ that He is the virgin born Son of God, that He died on the cross to pay our sin debt, that He was buried and that He rose from the dead.
