The following story, one of the best that I've read, explains the existence of God...
"Why do you say that?" asked the customer. The barber replied: "Well, you just have to go out in the street to realize that God doesn't exist. Tell me, if God really exists, would there be so many sick people? Would there be abandoned children? If God existed, there would be neither suffering nor pain. I can't imagine a loving God who permits all of these things."
The customer thought for a moment but didn't respond to avoid an argument. The barber finished his job and the customer left the shop. Just after he left the barber shop, he saw a homeless man in the street with dirty, long hair and an untrimmed beard. The customer immediately entered the shop again and said to the barber: "You know what? Barbers do not exist!"
"How can you say that?" asked the surprised barber. "I'm a barber and I'm standing right here. And I just worked on you!"
"No!" the customer exclaimed. "Barbers don't exist because if they did, there wouldn't be people with dirty long hair and untrimmed beards, just like that man outside your shop!"
"But barbers do exist. That happens when people do not come to me." said the barber. "Exactly!" affirmed the customer. "That's the point. God does exist! See what happens when people don't go to God and do not look for Him? That's why there is so much pain and suffering in the world."
Although many people question how God could create a world involving so much evil, the fact is that most of the pain and suffering in the world is caused by man's own inhumanity to mankind. I believe God exists. Why? As a Christian, I can sense God's presence, feel His love and sense His leading as I go through life's journey. Miracles have happened in my life and there are no other possible explanations other than God's interventions. God has saved me and transformed my life that I can't help but praise Him and acknowledge His existence!
God has indeed provided overwhelming evidence of His existence through His creation. God will not force anyone to believe in Him. Instead, God wants people to respond to Him willingly. To those who want to know if God exists, He says, "You will seek me and find me when you seek me with all your heart. I will be found by you." (Jeremiah 29:13-14 NIV)
