Whatever you can tolerate, you cannot change. Become tenacious. Resist sickness. Cling to the Healer.
Your persistence will demoralize Satan and attract the attention of God. Demons dread a fighter.
“And, behold, a woman, which was diseased with an issue of blood twelve years, came behind him, and touched the hem of his garment: 21 For she said within herself, If I may but touch his garment, I shall be whole.”
(Matthew 9:20-21)
