In Matthew 22 Jesus informed the Saducees that the cause of their confustion, the path that led them away from the truth and the hindrance of them drawing closer and having fellowship with Christ was their ignorance of the word of God, and their minimalist view of God. So it is with us today; much if not all of what makes us anxious, confuses us, hinders and overwhelms us is that we aren't governed by His truth and we are not resting secure in His power.
