Luke 16:31 KJV
And he said unto him, If they hear not Moses and the prophets, neither will they be persuaded, though one rose from the dead.
God's Word says that the Moses (the Law) and the prophets is what persuades a man to turn to Christ. Miracles, though used to verify that Jesus is Lord, never have persuaded men to come to Christ. Jesus raised,
• Jairus' daughter
• The widow of Nain's son
• Lazarus, and then
• Rose again Himself
Still numbers are left unpersuaded.
Salvation comes through faith and not impression. No man will come to salvation because something strikes awe in him.
Faith is only and always the gift of God, passed on through hearing the Word of God. So we must tell the Word.
