Revelation 21:4 NIV

"He will wipe every tear from their eyes. There will be no more death or mourning or crying or pain, for the old order of things has passed away."

Kathryn Butler, Trauma and Critical Care Surgeon said,

When it comes to praying for healing or receiving healing from God, there’s one important distinction we should make, i.e., Although God can heal us, we must never presume that he must.
