It's hard to come to conclusions quickly, but I'll see what I can do about that.
One statement people usually use to argue against God is :"He never answers my prayer." They believe that a perfect being will give them what they want, when they want it, which is kind of weird. The Bible tells us God made us for companionship, which is more of a friend to friend approach, right? Would you expect your best friend to do whatever you want because you want it? Not really. Than why should you expect that from God? Because he's perfect? That would be silly, seen as he knows exactly what you really
need, not what you
want.
Another thing as that we can't see, hear, smell, touch, or whatever else to prove he's around. However, we can see his creation, but most people would argue that's not enough. The only thing I can say on this is that God would explain the things science can't. Remember when that cancer patient lived when they were deemed dead by a trained doctor? Those things can easily be explained when you consider God.
Also, I've been asked why God would let people get sick if he loves us so much. There was a time where we disobeyed God, and he told us that if we did disobey, we'd get sickness, disease, death and pain. We brought this upon ourselves, it was not God's fault. Consider this, if you get yourself 1 million dollars of debt, would you walk up to your best friend and demand they pay off your debt? No, because you were to blame and what did they have to do with it? Same with God, why should we expect him to pay of our debt when we are to blame, and likely we'll all into debt again.
I may have swerved off topic, so let's continue with the big subject. To be honest, it's incredibly difficult to show that God does exist, but it's super easy to disprove why he doesn't, in fact I can pull apart every single argument against God, but to straight out prove his existence is hard when we can't observe God. I have brought two atheists (Both professors in philosophy) to believe in the existence of God, and to this day they continue to explain to other professors and doctors of philosophy the proof for God. All I can say is that I am not religious, I never will be. But I certainly am convinced of late that God exists.
