When Jesus encountered a man who was born blind, the disciples became concerned about the cause.
They asked, "Whose sin caused this?"
We tend to be so much like the disciples. We want to know where the sickness came from, so we spend hours searching Google to study the cause and potential solutions.
Do you know what Jesus has to say about this?
Don't concern yourself with the cause. Fix your thoughts on what God wants: to be glorified through healing.
God's will is to heal everyone every time. Jesus demonstrated this for us. He never refused healing. He had an unlimited supply for everyone who came to Him in faith.
Learn to live life where the cause of sickness is irrelevant.
The only thing that matters is bringing glory to God by receiving the healing that's already been paid for by the blood of Jesus Christ.
