Matthew Henry Presbyterian @wholebiblehenry

The way of wisdom and holiness is here recommended to us, 1. As very safe and comfortable: It is the way of life, the way that leads to eternal life, in which we shall find the joy and satisfaction which will be the life of the soul, and at the end of which we shall find the perfection of blessedness. Be wise and live.
