" And He (Jesus) went about all Galilee , teaching in their synagogues and preaching the good news (Gospel) of the kingdom, and healing every disease and every weakness and infirmity among the people."
After reading this passage of scripture there is no doubt that Jesus healed ALL their diseases. In the church I first attended we would see the power of God move and nearly every Sunday someone would testify of how God healed them. There was no way you could deny God's healing power was evident within the congregation.
In Matt 10 : 8 Jesus sends out the disciples telling them to preach the good news, cure the sick, raise the dead and drive out demons. So when we pray in the name of Jesus we have the same authority He had and we believe those prayers will be answered. I have seen this happen when I've prayed for others and I have experienced my own healing aswell.
One of my favourite books in the bible is Isaiah. In chapture 53 verse 4 and 5 we read when Jesus died on the cross it wasn't just for our sins but also all our diseases. He was wounded for us so we are healed and made whole. This healing is still available to us today. I would encourage you to continue to lean on, trust , and be confident in Him, (Jesus) with all your heart and mind. Nothing is impossible for God.
