Thank you for your responses everyone. I know there will be people who don't believe that God still speaks to people. I happen to believe God DID guide this man to build the dam. I've had an experience with God myself. It happened when I forgave my mom for what she has put my dad and I through. (long story). Basically I said to myself "Jesus if you're real, I will forgive my mom for all that she has done." and I was stunned when I heard an audible voice say "Now you understand my daughter." You can think I am crazy, but I would swear on my life it happened. I was agnostic before this happened. I then had an encounter with the Light of Jesus and I felt the most overwhelming love I had ever felt in my life.
This happened when I was alone in my bedroom. He told me he was God. I was in shock. I am not sure how long the experience lasted but I felt like I was in eternity. Being in his presence feels more real than reality. It's like a hyper reality. I don't know why Jesus doesn't appear personally to everyone. I honestly wish he would. He told me "you must have faith." As an agnostic, I never understood why faith was so important. But it IS important to him. I probably sound like a lunatic but I now have faith and it's changed my life for the better. I had also asked him why I was so depressed all the time. He said "You forgot that I love you." It was a very profound experience. And I know it's hard to share without sounding insane but I did research online and found other people who have encountered Jesus as well. He wants people to have faith in him. There are actually tons of people online who have experienced Jesus either through a near death experience, or through the type of experience I've had. Not all of them can be lying. I know I'm not. God bless you all
