Be not deceived; God is not mocked. Let us not be weary in well-doing: for in due time we shall reap, if we faint not.".
Hence the Son is said to be the Father's face, being the revealer of the Father's character to the five senses by clothing Himself with flesh. "But if we live in the Spirit, let us also walk in the Spirit."
Ver. 25. "If we live by the Spirit, by the Spirit let us also walk,"
— being governed by His laws. For this is the force of the words "let us walk," that is, let us be content with the power of the Spirit, and seek no help from the Law. Then, signifying that those who would fain have introduced circumcision were actuated by ambitious motives, he says,
What he means by “walk by the Spirit” is “let us be content in the power of the Spirit, and let us not seek to augment it with the law.” Then, having shown that those who introduce circumcision are doing this through ambitious motives, he says, “Let us not become proud, which is the cause of evils, calling one another out to factiousness and strife, in jealousy of one another. For jealousy comes from vainglory, and from vainglory all those other evils.”
(Verse 25.) If we live by the Spirit, let us also walk by the Spirit. Let us use this testimony against those who do not want to understand the Scriptures spiritually. But who is the one who lives by the Spirit, if not our hidden self, who sometimes tends to live according to the flesh? But when he lives by the Spirit, he walks by the Spirit. When he desires to walk in the flesh, he is alive but dead. The perfect man in Christ always lives in the Spirit: he obeys the Spirit, he never lives in the flesh. And on the contrary: He who gives himself entirely to the flesh and devotes himself to passions never lives in the spirit. Among these there are those whom we cannot call spiritual or carnal; but those who fluctuate between virtues and vices, sometimes being drawn back to better things and being spiritual, sometimes being tripped up by the slippery slope of the flesh and being carnal.
[AD 215] Clement of Alexandria on Galatians 5:25
Hence the Son is said to be the Father's face, being the revealer of the Father's character to the five senses by clothing Himself with flesh. "But if we live in the Spirit, let us also walk in the Spirit."
