What does it mean that God is our sustainer?

The truth that God is our sustainer runs through Scripture in two great streams: first, that Christ sustains the entire created universe by His divine power; and second, that He sustains His people personally through every trial, need, and weakness of their journey through this world.

Christ the Sustainer of All Creation

The foundation lies in the Person of Christ Himself. He is not merely the Creator who set the universe in motion and stepped back — He is the One who holds all things together moment by moment.

Hamilton Smith draws attention to the Colossians passage:

In Colossians we learn that the glory of His Person demands the place of exaltation. If He is "the image of the invisible God, the firstborn of all creation," the One by whom all things were created, who is before all, and sustainer of all, then indeed He must "in all things" have the preeminence.

William Kelly unfolds this from Hebrews 1, where the Son is described as "upholding all things by the word of his power":

Christ's maintenance of the universe presents His divine glory in a striking way. "By Him all things consist," as the apostle affirms in Col. 1. They were created by Him and for Him, and they subsist together in virtue of Him. This becomes all the more remarkable because He deigned for the deepest purposes to become true man. This, however, trenched not on His deity … As He therefore brought all into being, so does He sustain all the universe, and ever did so.

William Kelly

Kelly presses this further with a striking observation about the cross — even at the very moment when Jesus bowed His head and died, He was sustaining all creation:

Yes, the very Man whom they crucified by the hand of lawless men, who was crucified through weakness! At the moment He bowed His head and expired, He was sustaining all creation. It were absurd to think or say so, had He been only man; but He was God; and the dissolution of the tie between the outer and the inner man in no way touched His almighty power.

T. W. Mawson gathers these glories together:

Great and varied are the glories that He bears in this chapter, glories upon which no creature could lay his hands, or claim a title to. He is the Redeemer; the Image of the invisible God; the Creator of all things, and the End for which they were all made, and He sustains the universe that He has made by His almighty and undiminished power.

T. W. Mawson

Christ the Sustainer of His People's Life

The same Christ who upholds all things by the word of His power is the One who sustains His people personally — through daily needs, trials, and weakness.

F. B. Hole, writing on John 6, draws out this double character of Christ as the "bread of life":

In natural things bread only sustains life and in no sense gives it; but the spiritual always transcends the natural. The material figure serves to direct our thoughts to the Divine fact, but can never contain its fulness. Jesus was here as both the Giver and the Sustainer of life.

F. B. Hole

Hole explains how the one who has received life by faith continues to live by faith — a sustained life:

The life that is received has to be nourished and sustained; hence the one who has eaten still eats; in other words, he who has received the life by the original appropriation of faith now lives on the same principle — "The just shall live by faith." He has believed, and he goes on believing.

The High Priest Who Sustains Us on the Way

A major dimension of God's sustaining work is through the present ministry of Christ as High Priest. William Kelly explains:

Therefore to sustain us and sympathise with us in our weakness He has given us a great High Priest, whose love to us we have already proved when there was nothing to love in us, whose blood cleansed us from every sin, whose death and resurrection set us free … We are not yet as He is in the heavenly land. We are journeying through the dry and howling wilderness.

William Kelly

T. W. Mawson adds the beautiful picture of how sympathy and power unite in this Priest:

We need to be sustained and succoured in this way of faith, for we are beset with infirmities and the road is not always easy to travel; we need a great High Priest, to sympathise with us and to succour us and to save us to the uttermost as we come to God by Him … He is Jesus, that tells us of the tender sympathy of His heart for us. He is the Son of God, that tells us of the power of His arm; the tenderest love and the greatest power in the universe abide in Him.

T. W. Mawson

A. J. Pollock puts it concisely:

The priesthood of Christ is founded on His death and resurrection. His priesthood sustains His wilderness people till the heavenly Canaan is reached in association with Christ, the High Priest of our profession.

A. J. Pollock

And again:

The shed blood of His cross gives us boldness to enter, and then His priesthood sustains us whatever our infirmity may be, so that we may, and can, draw near.

Sustaining Grace in Daily Trials

Hamilton Smith, commenting on Philippians 4, shows how this works out in everyday life. The believer, like a sheep — "needy, weak, and timid" — is upheld by the Lord Himself:

In this portion the Apostle give us the answers, as he sets before us the great Shepherd of the sheep — the One Who alone can lift us above every trial, meet our every need, and keep our feet in the heavenly path. The Lord had said to His disciples, "Without me ye can do nothing;" now the Apostle, having experienced the Lord's sustaining grace, can say, "I can do all things through Christ which strengthens me."

Hamilton Smith

Smith also draws attention to the experience of Psalm 94, where the Psalmist found inward sustenance amid anxious thoughts:

The Psalmist not only realised the sustaining grace of the hand of the Lord, that kept him in the presence of snares into which he was in danger of slipping, but he found that the "comforts" of the Lord sustained his soul when he was in danger of being overwhelmed by a multitude of "anxious thoughts."

Writing on Ephesians 6, Smith links the sustaining grace to the cares, sicknesses, and petty insults of the Christian life:

If, however, instead of allowing all these things to come between our souls and the Lord, we make them occasions for drawing near to the Lord, we shall learn what it is to be strong in the Lord, while realising our own weakness; and we shall learn the blessedness of the word, "Cast thy burden upon the Lord, and He shall sustain thee" (Psalm 55:22).

"Cast Thy Burden — He Shall Sustain Thee"

The invitation of Psalm 55:22 stands as a direct promise. L. M. Grant comments:

Thus, the godly are encouraged to cast their burden on the Lord, with the assurance, "He shall sustain you." Wonderful indeed is the certainty that "He shall never permit the righteous to be moved."

L. M. Grant

C. H. Mackintosh unfolds this with characteristic warmth:

Art thou, at this moment in any pressure, in any trial, need, or difficulty? If so, let us entreat thee to look simply and solely to the living God. Turn away thine eyes completely from the creature … Cast thy burden, whatever it is, upon Him. Let there be no reserve. He is as willing as He is able, and as able as He is willing, to bear all. Only trust Him fully. He loves to be trusted — loves to be used. It is His joy, blessed be His name, to yield a ready and a full response to the appeal of faith. It is worth having a burden, to know the blessedness of rolling it over upon Him.

C. H. Mackintosh

To say that God is our sustainer is to confess a truth that reaches from the farthest stars to the smallest details of daily life. At the highest level, Christ upholds the entire created universe by the word of His power — all things consist, or hold together, in Him. Were He to withdraw that sustaining word, all would collapse into nothing. At the personal level, that same almighty Person is occupied with His people as their great High Priest, sympathising with their weaknesses, interceding for them, and meeting every need with grace suited to the moment. He is the bread that sustains life, the shepherd who carries the sheep, and the One to whom every burden can be cast with the sure promise, "He shall sustain thee." The sustaining power of God is not a distant doctrine but a present, living reality — proved, as Mackintosh beautifully says, by the fact that "He loves to be trusted — loves to be used."
