The verses in question are from the prophet Habakkuk, the apostle Paul, and the writer of Hebrews (whom most believe was Paul):

Hab 2:4  the just shall live by his faith.

Rom 1:17  The just shall live by faith.
Gal 3:11  … The just shall live by faith.
Heb 10:38  the just shall live by faith

Clearly, Habakkuk 2:4 says “by his faith,” but when this prophet’s words were quoted in the New Testament, “his” was omitted. Why?

Old Covenant vs New Covenant 

There are many things that were different under the Old Covenant.  This is one of those things. 

In salvation under the New Covenant, we have been given the Holy Spirit to indwell, teach, direct, and seal us “unto the day of redemption.” (1 Cor 3:16, John 14:26, Eph 1:13, 4:30)  Under the Old Covenant that was not so.  

Before Jesus came and gave Himself to pay for the sins of mankind, and opened the way to the Father under the New Covenant, the Holy Spirit would come upon, or enter into, some of the people who trusted in Jehovah God.  The Spirit was given by God to prophets, priests, and kings to empower them in their service for God.  And, He could depart them at any time, especially in times of sin.  In contrast, under the New Covenant, the Spirit will never leave us.  We are guaranteed of His presence and that assures us of the security of our eternal life in Christ.

Spirit Produced Faith

One of the “works” of the Holy Spirit in us is to produce fruit.  And that fruit includes, love, joy, peace, patience, kindness, goodness, gentleness, faithfulness, and self control.  So how does the Spirit produce faithfulness in us?  By increasing our faith.  And how does He increase our faith?  By exactly what Jesus said He would do…by teaching us.

John 14:26  But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.

Our faith is built by knowledge.  

The reformers defined faith as:  knowledge + belief + trust = faith.  (Read: What is Faith?)  Therefore, we understand that the foundation of faith is knowledge.  And knowledge comes from the Word of God:

Rom 10:17  So then faith comes by hearing, and hearing by the word of God.

So the Holy Spirit gives, or increases, our faith by giving us knowledge—by teaching us all things (John 14:26).

The Just Shall Live by His Faith vs by Faith?

Because most believers in the Old Testament did not have the Holy Spirit, or did not have Him permanently, they did not have a spiritual Helper to grow their faith or direct their ways.  It was necessary that they keep their focus on God by prayer, obedience to His moral Law, and practice of the Levitical Law.   By doing these things they themselves would grow their faith and that’s why it’s said a just man would “live by HIS [own] faith.”

Under the New Covenant, our prayers, and our obedience and observance of all God’s precepts and principles, are influenced by the indwellling of the Holy Spirit.  He is active in the life of a believer.  Therefore, we live by faith — a faith produced not of our own singular ability,  but a faith produced by the working of the Holy Spirit in our hearts, minds, and souls. It is a faith produced by God’s faithfulness to us (Gal 2:20). And thereby we walk (2 Cor 5:7), stand (1 Cor 16:13), and live (Rom 1:17, Gal 3:11 and Heb 10:38), not by our faith but by faith that is strengthened by God.

1 Cor 1:9  God is faithful, by whom you were called into the fellowship of His Son, Jesus Christ our Lord.

Eph 3:20  Now to Him who is able to do exceedingly abundantly above all that we ask or think, according to the power that works in us,

Psa 89:1  I will sing of the mercies of the LORD forever; With my mouth will I make known Your faithfulness to all generations.

Praise God for His faithfulness to you, for the mercy and grace He has given you and for the faith He is building in you.

Live in the Strength of the Lord

1 Timothy 6:11 …Pursue righteousness, godliness, faith, love, steadfastness, gentleness.’

Eph 3:16-17  that He would grant you, according to the riches of His glory, to be strengthened with might through His Spirit in the inner man, that Christ may dwell in your hearts through faith; that you, being rooted and grounded in love,

Gal 2:20  I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me.
