Those athiests who say God doesn't speak, hasn't sought God with their hearts. God still speaks. You have to listen. He will not say or have you do anything contrary to His Word. His Word is Jesus. In the Old Testament, God showed His Holiness and His Hate of sin, thus demanding sacrifice. Jesus in the New Testament paid the sacrifice and rose from the dead. The New Testament shows Gods Love and Mercy. The entire bible is both sides of the same coin. There are thousands of testimonies where people have been at deaths door and saw or heard God and He sent them back. God works through His people today. Through faith you reach God, and He speaks with a "still small voice" to each believer. There are still miracles today. Doctors can attest to that.
