The Bible is not just a physical book, but it is spiritual in nature, having come from God Himself. That is why whenever the Scriptures talk about healing, it does not only pertain to a physical illness. There are illnesses that are spiritual, which in turn, require spiritual medicines as well.
Whether what you are going through is a physical, emotional or spiritual illness, God can help you get through and recover. But you have to come to Him in prayer, believing that you will receive from Him. Just like when the woman with an issue with blood approached Jesus and touched the hem of His garment, He said that it was her faith that made her whole.
Do you have faith in God? If you do, then ask Him about your health or illness. Whatever that problem is, God has an antidote ready for you.
