From Calvin’s Second Sermon on Psalm 119: BETH
“Wherewithal shall a young man redress his way? in taking heed thereto or standing upon his guard according to thy word.”
He showeth us here, that if we be desirous to order our life as it becometh us, to have it rightly governed, and to be pure and simple, we must hold that way which GOD hath set before us. For we must not trust unto our own wits. Neither frame and fashion unto ourselves such a way as shall to us seem best: but to suffer God to rule and conduct us, and to obey him simply and plainly. To be short, David signifieth unto us, that all the wisdom and perfection of our life, is to follow GOD, and cleave unto his will.
