Theories of evolution, origin of the Universe, and deep time, have led many scientists like my former self, to conclude that Creation is just a chance sequence of events that can ultimately be explained by natural laws. I was skeptical and even tried to disprove God's existence, until I found a Secret Code embedded in the Scriptures. This code provides undeniable evidence of God, based upon event sequences in the lives of a Great Cloud of Witnesses like Joseph, Samson, David, Jonah, Elisha, Moses, and Joshua. By unlocking the Earthly Sanctuary pattern given to Moses, I've found that it reveals events of the Exodus from Egypt to the Promised Land which even applies to Spiritual Israel today. The veil to the Holy Place aligns with the Exodus opening of the Red Sea. And the veil to the Holiest Place points to the opening of the Jordan where we now stand, waiting to cross at the End of Time. The code reveals probabilities of the existence of God, far greater than finding an atom in Planet Earth by chance.
