If God healed back then, it means that healing NEVER changes because He never changes.
Hebrews 13:8 tells us that He is the same yesterday, today, and forever. Healing is always going to be there.
We say, "These people need healing, so we're going to pray for them", or, "I need healing so I'm going to pray for it."
We want to see that even though Jesus healed everybody 2000 years ago when He went to the cross and bore in His own body all sickness and disease, we want to see healing being manifested today.
