>No, blessed is He who believes without seeing.
Yes, because when one believes in God's goodness they put forth in motion a call to the Divine and according to that faith is equal to the amplification of the signal.
>Faith is belief in the absence of knowledge.
Correct, faith is not the tangible manifested but the constant process of belief.
>Knowledge is not faith.
Correct. When faith is completed it becomes a specified knowledge regarding that faith. If the faith is never completed neither comes knowledge of.
Many have Faith in God, few have Fear of the Lord. If they did, they would act totally different.
Yes not many find it, but many think they found it.
