The Importance of Living by FAITH is to enable you to walk and function in the supernatural.
+Four times God said in the Bible, “The JUST shall live by FAITH”

“Behold the proud, His soul is not upright in him; BUT THE JUST SHALL LIVE BY HIS FAITH.”(Habakkuk 2:4 NKJV).

“For in it the righteousness of God is revealed from faith to faith; as it is written, “THE JUST SHALL LIVE BY FAITH.”(Romans 1:17 NKJV).

“But that no one is justified by the law in the sight of God is evident, for “THE JUST SHALL LIVE BY FAITH.”(Galatians 3:11 NKJV).

“Therefore do not cast away your confidence, which has great reward. For you have need of endurance, so that after you have done the will of God, you may receive the promise: “For yet a little while, And He who is coming will come and will not tarry. NOW THE JUST SHALL LIVE BY FAITH; But if anyone draws back, My soul has no pleasure in him.” But we are not of those who draw back to perdition, but of those who believe to the saving of the soul.”(Hebrews 10:35‭-‬39 NKJV).

+The word JUST in scripture means justified ( just as it we have never sinned). It also means RIGHTEOUS.
+We are the Righteousness (the JUST) of God by FAITH of Christ Jesus. See Romans Ch-3 & Ch-10
Hebrews 11:6
Without FAITH is impossible to please God.
+It takes FAITH in the Lord Jesus Christ to live in LOVE, TRUTH, HOLINESS and RIGHTEOUSLY, and Why?
Romans 14:23 says:
…for whatsoever is not of FAITH is sin.
+To go deeper whatsoever is not LOVE, TRUTH, HOLINESS and RIGHTEOUSNESS is sin.

Galatians 2:16 says :Knowing that a man is not justified (or made righteous) by the works of the law, but by the FAITH of Jesus Christ, even we have believed in Jesus Christ, that we might be justified (made righteous) by the FAITH of Christ…

+We are Righteous, Justified, Sanctified and made Holy because we live by the FAITH of the Lord Jesus Christ, and FAITH in His REDEMPTIVE WORK from His Birth to His Resurrection, Ascension and Him coming back again.

+Through Faith, we live in the Resurrection Power, Healing Power, Deliverance Power, and the Protective Power of our Lord Jesus Christ for Long Life, Prosperity, and Good Success. “Now to Him who is able to keep you from stumbling, And to present you faultless Before the presence of His glory with exceeding joy, To God our Savior, Who alone is wise, Be glory and majesty, Dominion and power, Both now and forever. Amen.” [Jude 1:24‭-‬25 NKJV].

Continue to let the WORD of God be the standard for your life. Always LOVING others like Christ Jesus loves us while keeping our Faith, Trust, and Confidence in Him.

BLESSED you are and BLESSED you will always be and to God be all the GLORY. Amen!
