Greetings and peace be with you Muslimah_Sis; and thank you for your reply,
Faith in god requires that we should obey him and not sin, we should also have absolute faith in a loving and merciful God who can heal.
Sadly this is so difficult to strive towards; here is a short passage bout the disciples after they failed to heal a boy.
Mathew 17
17"O unbelieving and perverse generation," Jesus replied, "how long shall I stay with you? How long shall I put up with you? Bring the boy here to me." 18Jesus rebuked the demon, and it came out of the boy, and he was healed from that moment.
19Then the disciples came to Jesus in private and asked, "Why couldn't we drive it out?"
20He replied, "Because you have so little faith. I tell you the truth, if you have faith as small as a mustard seed, you can say to this mountain, 'Move from here to there' and it will move. Nothing will be impossible for you."
Very few people can achieve that real faith in the healing power of God; yet I believe that it is open to any of us.
In the spirit of striving for a greater faith
