1 The divine lessons raise us up, that we be not broken by despair; and terrify us again, that we be not tossed to and fro by pride. But to hold the middle, the true, the strait way, as it were between the left hand of despair, and the right hand of presumption, would be most difficult for us, had not Christ said, “I am the Way, and the Truth, and the Life.” As if He had said, “By what way would you go? 'I am the Way'. Whither would you go? 'I am the Truth.' Where would you abide? 'I am the Life.'”
Let us then walk with all assurance in the Way; but let us fear snares by the way side. The enemy does not dare to lay his snares in the way; because Christ is the Way; but most certainly by the way side he ceases not to do so. Whence too it is said in the Psalm, “They have laid stumblingblocks for me by the way side.” And another Scripture says, “Remember that you walk in the midst of snares.” These snares among which we walk are not in the way; but yet they are “by the way side.” What do you fear, what are you alarmed at, so you walk in the Way? Fear then, if you forsake the Way. For for this reason is the enemy even permitted to lay snares by the way side, lest through the security of exultation the Way be forsaken, and you fall into the snares.
