As I understand it, faith is the certainty in one’s belief in some thing or someone. Of course in the context of spirituality, faith usually refers to one’s certainty in the existence of a higher being, Universal Energy, or Creator.
When we say we have faith in a person, we are letting them know that we trust them or have trust in them—trust in their abilities, trust that they will not do anything to hurt us, trust that they will be there when we need their help or support.
It could be said that our faith in God has these same attributes and expectations. However, our faith in God is intuitive and comes from spiritual awareness, whereas our faith in a person is experiential and based on concrete knowledge of their past behaviors. Consequently, faith in a higher being is a leap that some are unwilling to take.
Another form of faith refers to trust in a religious doctrine and what are believed to be God’s promises and teachings found in religious scriptures. I believe that one should be cautious here and not let this type of faith to be blind. The scriptures and the clergy should not go unchallenged.
Scriptures from the various religions provide a lot of wonderful guidance concerning how to live a spiritual life of goodness. I think that most of us would independently agree on which passages provide such spiritual wisdom.
However, skepticism about other passages is healthy and may provide deeper insight. We would be remiss if we blindly accepted everything in the scriptures as the word of God. We were given the ability to reason and, if we apply it, we will be able to distinguish the word of God from those of men.
