There is not a single case where Jesus made someone sick, or where Jesus refused to help a sick person by saying that God wanted them to be sick.
God does not want us to be ill. A God who tells us, “I am the Lord, who heals you.” (God in Exodus 15:26; NIV).
A God about whom we are told: “The Lord will keep you free from every disease. …” (Deuteronomy 7:15; NIV). Begin to believe God, not the demonic lies that try to make you question God’s glorious, loving nature who wants to bless you out of His abounding love for you.
