Benjamin Franklin was most probably not a Christian. While none but God knows for sure the state of any particular persons soul and stand before Him, his life and personal memoirs seem to indicate that at most he was a Deist. Nevertheless he had great respect for God, the Bible and prayer.
During the Constitutional Convention in 1778 tempers were flaring. At one point the debate had become so heated that things appeared they would dissolve in failure. Benjamin Franklin (by then 81 years old) stood up. The delegates one by one fell silent out of respect for this elderly statesman. Benjamin Franklin then addressed the men assembled:
I have lived a long time, and the longer I live the more convincing proofs I see of this truth: the God governs in the affairs of men. And if a sparrow cannot fall to the ground without His notice, is it probable that an empire can rise without His aid? We have been assured, Sir, in the sacred writing, that “except the Lord build the house, they labor in vain that build it.”
Franklin then suggested that the men assembled begin each morning with prayer, asking for God’s guidance and wisdom. From that day forward, the convention proceeded smoothly.
