The just shall live by faith.
The faith that is living faith.
The term “living faith” is strictly accurate; because faith really is a living thing. The just live by faith, and you can’t live by something that has no life in it. As you can live only by that which brings life to you, and as you live by faith, it is plain that faith is a living thing. Faith is the gift of God (Eph. 2:8) and He is a living God; Jesus is its Author (Heb. 12:2), and in Him is life He is the life. In the nature of things, that which comes from such a source must be of itself imbued with life.
And as faith comes wholly from Him who is the only living God, from Him who alone has life, and not from ourselves (Eph. 2:8), it is certainly imbued with life, and so brings life to you by which you may live indeed.
Faith comes by hearing the word of God (Rom. 10:17); that word is “the faithful word” (Titus 1:9), that is, the word full of faith; and that word is “the word of life.” Phil. 2:16. Therefore as the word of God brings faith, and is full of faith; and as that word is the word of life, it is evident that faith is life. It is a living thing and it brings life from God to you as you exercise it.
What life is it that faith brings to you? Coming as it does from God, through Jesus Christ who is the “Author of life,” the only life with which it is imbued and which it could possibly bring to you is the life of God. The life of God is what you need and what you must have. And it is the life that God wants you to have; for it is written: “Walk not as other Gentiles walk, in the vanity of their mind, having the understanding darkened, being alienated from the life of God.” Eph. 4:17, 18.
