Hebrews 11:6

"And without trust it is impossible to be well-pleasing; for the one who cometh to Placer must trust that Placer existeth, and a hire-from-giver of those who seek after him."

The Greek word PISTIS has a broader semantic range than the does our English word "faith."  In an attempt to reflect the ultra literal meaning of the word, the Etymological New Testament consistently uses the word "trust."  It is critical to understand that Biblical "trust" is based on what we know.  Too often the reverse is proclaimed.  Too often, we are in de facto agreement with Huck Finn: "Faith is believin' what you  know ain't so." 

It is because of our experience of the Spirit of God (Placer) that we know.  And because we know, we trust.
