Trusting God is not by what you read or know.  It is by doing what you have learned from His Word, Bible.

From James 1:22-25:  “But be doers of the word and not merely hearers who deceive themselves.  For if any are hearers of the word and not doers, they are like those who look at themselves in a mirror; for they look at themselves and, on going away, immediately forget what they were like.  But those who look into the perfect law, the law of liberty, and persevere, being not hearers who forget but doers who act—they will be blessed in their doing.”
