First,a MAN called Jesus did exist. This is a "fact" that you don't have to believe. But if you believe "what Jusus walked around and taught people" or not takes faith.
Proof of God's existence---I don't have it in a material form.
But I suppose you know God's basic message is LOVE. This is not limited to boy and a gorl thing. It is easy to love someone we already love. Love God talks about is Humanity..caring and helping others. People tend to imagine "god's answer to your prayer" is something like a big dramatic lighting or big whilt light comes from sky.... and when we don't see it we tend to think "there's no such thing as God" ... but that's not how God works. We just don't take notice that God is trying to help us in his own way.
Here's a story to make it easier to understand:
There was a man,who believed in God. He read his bible, went to Church, did all the good things, never committed any crime.
One day,storm was approaching. He heard the place where he lived would be flooded. He didn't worry, he thought "I believe in God. God will help me". When it started to rain, neighbors told him they would help him evacuate, but he told them "no thank you, I believe in God. God will help me, so I don't need your help". Then it started to flood, so the man went upstaris. Someone came to rescue him on a boatCome on, we will help you! get on the boat!" but the man told themNo thank you, I believe in God, God will help me, so I don't need your help". Water got higher, the man had to crimb up to the tree from the roof. A helicopter came. "We will help you! grab the ladder!"...again, man told themNo thank you, I believe in God,God will help me, so I don't need your help"...and he died.
when he went to heaven, he asked God "God why did you not help me?"
God became angry and shouted at him. "YOU FOOL! I TRIED TO HELP YOU! I SENT YOU BOAT AND HELICOPTER AND EVERYTHING!"
Of course this isjust a story, not real... But I hope you can get an some idea how God works to make us "help each other". If we ask God and God gives whatever we need directly, we won't have a chance to work together, helping each other, lending hands to the weak,helping poor, caring for the sick....
I hope it helps you see from my point of view a little...
sorry it took so much space..
