Before when myself full of doubt I always question God if He hears my prayer because nothing changes in my life, still my life was full of struggle and suffering which is why I can’t avoid questioning God. But after converting to a Christian I learned and realized that everything has a right time.
I learned that I went through that hardship because God has a reason and He has a bigger plan for me that is why He didn’t hear my prayers because those prayers are worldly things.
I believe that God hears all our prayers, keeps praying, and answer that prayer at the right time.
