Yes. We all know something of God without having to trust other people. Briefly, the creation points to a Creator, and the blessings we enjoy daily point to a Creator who is benevolent. Christ Himself is the light who enlightens everyone through the conscience. Hence deep down we know of right and wrong, of a duty to be good, and of a failure to be as good as we ought. We perceive that nevertheless life, especially human life, has intrinsic worth. We sense that life should have meaning and purpose beyond what we can assign to it ourselves, and some of us are confident that our lives do have a greater purpose, even if we cannot fully articulate it. We perceive that love and self-sacrifice are most excellent virtues and find ourselves expecting that these virtues should be found in God Himself, indeed we perceive that He is the true ground of all virtue and transcendent meaning. We would expect love to be communicative and adapted to our capacities for reception and so it is reasonable for us to look for a revelation somewhere in the world, especially one that claims to have a history. This knowledge may have been passed down through human instruments, but it requires us only to trust in the God who is Love, a God who has seen to it that whatever knowledge we need, whatever guidance essential to life, has reached even to our generation. Our needs are our claims on Him. At this point, the prophecies of the Bible fulfilled in Jesus Christ may speak to us themselves, along with the noblest morality ever taught and the worthiest views of God ever preached, carrying their own evidence with them, commending themselves to our conscience. If we are but willing to do God's will, we shall know whether Jesus spoke of Himself, as merely another man like us, or whether He brought a message from His Father and ours, whether in His words and deeds He has revealed God as never before. What hinders you from praying to Him now? from starting to put His words into practice? Will not action will cast fresh light on the whole matter, light not requiring you to trust other humans? In His light, we see light for ourselves.
