God’s existence must be accepted by faith, God has also revealed Himself to us through His Word and the Bible and there is also evidence of God in our own hearts, how do I know God exists? because I speak to Him every day but I do not hear Him speaking back to me, but I sense His presence and I know His love and things have occurred in my life that have no other possible explanation other than God...Some of us know that God is real because He has revealed Himself to us in three ways: in creation, in His Word, and through His Son, Jesus...That's enough proof for me to believe that God really exists...
