It is said that the inability to explain the complexities of the universe is not an argument for a Creator. The ability to explain so much of the universe - that IS an argument for a Creator - that is the main argument. His wisdom in making it makes so much of it explicable. Yet the experiential tacit knowledge that comes because of the Messianic sacrifice when that sacrifice is preached is the perfect way to know the Creator and demonstration of His power is the perfect way to believe in Him. Tacit knowledge cannot be shared so you might be unable to prove what you tacitly know through experience yet this truth can include certainty that the Messiah died for sins and lives today and lived thousands of years before He came, sent by God His Father.
