In these passages is the account of Jesus healing the blind man in Jericho. As Jesus and the multitude were passing by, the blind man called out to Jesus asking Jesus to have mercy on him. Jesus stopped and asked the man, “What do you want me to do for you?” The man said, “I want to regain my sight.” Jesus restored his sight and said, “Your faith has made you well.”
The blind man demonstrated his Faith in Jesus by publicly imploring Jesus to restore his sight. He believed in Jesus, that Jesus could restore his sight. He had no doubt.
So, it is with us. Our demonstrated Faith in Jesus Christ will heal us of our afflictions and lead us to Heaven. However, we must read the Bible to know how our Faith should manifest itself. Jesus is the living Word of God. Reading the Bible is the only way to know Him.
