To walk straight to God is to walk in love. This is the way of the undefiled who, as the Psalmist says, “seek Him with their whole heart” (Ps. 119:2), thereby showing what is the desire which has been enjoined upon us. Those who “walk in the law of the Lord” (Ps. 119:1) are those who live in love, the commandment on which the whole law depends (Mt. 22:40). They do so in order that they may straightway strip themselves of all sin, which alone obscures the vision of the soul.
