What does it mean to believe in the sufficiency of Christ?
Believing in the sufficiency of Christ means being convinced that God has put everything a person needs into one Person, and that nothing outside Him needs to be found or added. It touches how you get peace with God, how you face pressure, and what you refuse to lean on.
Where the conviction begins
The belief is not usually reached by argument. Writers describe it as what a person discovers when self-confidence has completely collapsed.
C. H. MackintoshThe true secret of peace is to get to the very end of a guilty, ruined, helpless, worthless self, and there find an all-sufficient Christ as God's provision for our very deepest need. This truly is rest — a rest which can never be disturbed. There may be sorrow, pressure, conflict, exercise of soul, heaviness through many temptations, ups and downs, all sorts of trials and difficulties; but we feel persuaded that when a soul is really brought by God's Spirit to see the end of self, and to rest in a full Christ, it finds a peace which can never be interrupted.
The same writer traces restlessness among believers back to this point. Where peace is missing, the cause is often not a fresh sin but a small Christ.
C. H. MackintoshThe unsettled state of so many of God's dear people is the result of not having received into their hearts a full Christ, as God's own very provision for them.
Fullness in Him, completeness for us
Colossians grounds the claim in who Christ is. The argument runs in two directions at once — what comes down to us, and how we stand before God.
Hamilton SmithNot only is God fully revealed to us in Christ, but believers are fully presented before God in Him. All the blessing that God has purposed for believers, and that Christ's work has secured for believers, is set forth in Christ Himself, in His place in the glory above every principality and power. Our portion and position, as set forth in Christ, is complete.
One writer puts the personal side of that completeness sharply, as a matter of what I am, not only what I have.
The Christian's FriendNot only have I all I want, but I am all I need to be, in Him. I must appear before God, I have to deal with God, as a responsible being — looked at as to what I am in myself, I am lost; in Christ, I am complete, as complete as Christ is, for I am complete in Him.
Why additions are not neutral
If Christ is enough, then supplements are not harmless extras. They are a verdict on Him.
C. H. MackintoshIf we are leaning upon our fancied goodness, upon any righteousness which we think we possess, upon not having done any harm to anyone, upon our not being worse than some of our neighbours, upon our church membership, upon our attention to religious ceremonies; if we are leaning upon any or all of these things, or if we are adding these things to Christ, then we may be sure we are not ready in title, not ready in conscience... To bring anything else is to declare that Christ is not needful: to bring anything besides is to affirm that He is not enough.
The additions do not merely fail to help. They work against what they claim to improve.
J. N. DarbyPhilosophy goes no further: it could not give us anything, much more where the truth of God is in question; anything we find added only tends to destroy... So the Christian should seek for nothing outside Christ. We are in Him in whom all fullness dwells: what can we want more? We are complete and perfected in Him.
Sufficient across the whole of life
Sufficiency is not only a doctrine about salvation. One treatise divides it across the three areas where a person actually needs help.
C. H. MackintoshThere is treasured up for him in Christ all he can possibly need, whether it be to meet the claims of his conscience, the cravings of his heart, or the demands of his path. We shall seek, by the grace of God, to prove that the work of Christ is the only true resting place for the conscience: His Person, the only true object for the heart: His word, the only true guide for the path.
That reach has no exceptions, and it covers groups as well as individuals.
J. N. DarbyIt is a blessed truth that we cannot be in circumstances Christ is not sufficient for. Whether it be the church or individual saints, it is impossible to be in a place for which Christ is not sufficient.
Weakness as the proving ground
Paul's thorn is where the belief was tested rather than merely stated. The size of the supply and the size of the need are deliberately mismatched.
J T MawsonThere is the ocean of grace at one end of the sentence, and the thimble of our need at the other, and the ocean is enough for the thimble; and that not for special days of stress only, but always and for all.
Even a man who already lived by dependence found there was more to learn.
William J HockingHe habitually leaned upon that grace, and not on his own strength... His ordinary course was not to go on, like many in a spirit of careless, unconscious independence, until some great difficulty made him feel his dependence and turn to the source of his strength. But even he had to learn that there was a fuller sufficiency in Christ's grace than he had ever yet experienced, or even imagined.
Summary
- Emptied. The belief starts at the end of self, where an all-sufficient Christ is received as God's provision for the deepest need.
- Filled. All the fullness of the Godhead dwells in Him, so God is fully revealed to us and believers are fully presented before God in Him.
- Closed. Because He is enough, adding anything declares He is not needful — and what is added tends to destroy rather than improve.
- Wide. His work meets the conscience, His Person satisfies the heart, His word guides the path; no circumstance exists that He is not sufficient for.
- Proved. The ocean of His grace is set against the thimble of our need, and even Paul kept discovering a fuller sufficiency than he had imagined.
