Are you looking for proof that God is real? If so, I can help you with your research. If you want concrete proof look at the trees, look at the stars, look at the moon, but most importantly look at yourself! Your own human body should be proof enough to show anyone that we didn't create ourselves.!
I will share a short testimony with you about the existence of God.
I went to jail then to prison a few years ago. While I was in the county jail in a cell by myself, I experienced the darkest hour of my life. I had given up on myself. I didn't desire to live anymore. Despair became my best friend! I thought of ways of ending my life. But at my lowest point or darkest moment, I received a visitor to my cell. The visitor was the spirit of God! He personal came and touched my heart and restored hope and gave me a reason to continue living.
I'm sure this short testimony may sound unbelievable to you, but I declare to you that its the truth! I cannot give you physical proof that God exists, but I can let you know that He visited me in the county jail to let me know that He is real!
