Yes, if you believe, He will respond, but you don't seem to believe even when I give you real-life examples. "And He did not do many miracles there, because of their unbelief." (Matthew 13:58)
Another relevant one: My grandmother had diabetes and had her leg amputated many years ago. She suffered greatly as a result of this. All of her children and grandchildren came to see her before she died. I was saddened to see her pain. So I prayed to God "I know you're powerful, and if you're willing, you can heal her to the point where SHE GETS HER LEG BACK. I wish you could return her LOST LEG ". That night, I had a dream about my grandmother, and she had regained her leg. I was stunned and asked how she regained her leg. She said, "It is from God," but I was terrified, thinking she was a demon. I quickly cited God's name three times to cast out this demon! "What are you shouting for?" she asked, and I awoke. Then I realized that even if God did exactly what I asked, the world, including myself, would not accept this miracle. She died a week later.
Do you recall that Sadducees are also among the people's leaders, but they do not believe in the existence of angels, even though they are clearly recorded in the scriptures they read? (Acts 23:8) Many people appear to be like them.
2 Tim 4:20 - We don't know why Trophimus was left sick, but I recall Jesus purposefully letting Lazarus die before resurrecting him. We won't know Lazarus was resurrected if the disciples end the gospel book before Jesus resurrected him.
Phi 2:25-30 - Epaphroditus was on the verge of death, as mentioned in v27, and it was recorded that God had mercy on him, sparing Paul from grief. v28 says to send him so the people can see and rejoice. So Paul let the people rejoice over his nearly dead body, or a healed body that escaped death because of the mentioned God's mercy that 'spared Paul from sorrow'?
