Truth in Buddhism

Many (all?) religions contain elements of truth. It is logical that they would because humans have an intrinsic sense of morality and because false religions are (I suppose) produced by people who have knowledge of the Truth.
At Campus Ambassadors last Thursday I listened to a young Buddhist speak about his spiritual path. He seeks to listen to God (whom he defines as energy and not a personal being) through meditation. While he does not think there is any one correct dogma, his main basis for decisions seemed to be "do unto others as you would have them do unto you."
I agree with him on various levels. Introspection using common sense, observation of the world, and observation of one's own thought processes can lead to a good deal of wisdom. Additionally, God speaks to Christians when they commune with him in prayer. I suppose that God probably speaks to Buddhists who are truely seeking him - perhaps he would eventually lead them along their spiritual path to accept Christianity. The Golden Rule is definitely a Christian principle.

As religions go, Buddha did a pretty good job formulating his ideas - but he missed some key truths by not accepting Scripture as a revelation from God. God can be found through inwardly seeking him, but he also gave us his word (written and in flesh) that we may know truths that would not otherwise be clearly apparent to us. Eg, truths about the purpose of man, the relation of God to man, salvation of souls, the purpose of animals, eternal destiny, the creation of the world, etc.
