Albert Barnes Commentary 1 Corinthians 10:12

"Wherefore let him that thinketh he standeth take heed lest he fall." — 1 Corinthians 10:12 (ASV)

Therefore. As the result of all these admonitions. Let this be the effect of all that we learn from the unhappy self-confidence of the Jews: to admonish us not to rely on our own strength.

That thinketh he standeth. This refers to someone who supposes himself to be firm in the love of God and in the knowledge of his truth, who regards himself as secure, and who will therefore be disposed to rely on his own strength.

Take heed lest he fall. Into sin, idolatry, or any other form of iniquity. We learn here:

1. that a confidence in our own security is no evidence that we are safe.
2. that such a confidence may be one of the strongest evidences that we are in danger. Those are most safe who feel that they are weak and feeble, and who feel their need of Divine aid and strength. They will then rely on the true source of strength, and they will be secure.
3. that all professing Christians should be admonished. All are in danger of falling into sin and of dishonoring their profession. The exhortation cannot be too often or too urgently pressed, that they should take heed lest they fall into sin. The leading and special idea of the apostle here should not be forgotten or disregarded: It is that Christians in their favored moments, when they are permitted to approach near to God and when the joys of salvation fill their hearts, should exercise particular caution. For:
   1. then the adversary will be especially desirous to draw away their thoughts from God and to lead them into sin, as their fall would most significantly dishonor religion.
   2. then they will be less likely to be on their guard, and more likely to feel themselves strong and not to need caution and concern.

   Accordingly, it often happens that Christians, after they have been particularly favored with the tokens of Divine favor, soon relapse into their former state or fall into some sin that grieves the hearts of their fellow believers or wounds the cause of religion.

So it is in revivals; so it is in individuals. Churches that are thus favored are filled with joy, love, and peace. Yet they become self-confident and elated; they lose their humility and their sense of dependence; they cease to be watchful and prayerful, supposing that all is safe. The result often is that a season of revival is succeeded by a time of coldness and decline.

And thus, too, it is with individuals. Just the opposite effect is produced from what should be, and from what is truly necessary. Christians should then be particularly on their guard. If they then made use of their elevated advantages, churches might be favored with continued revivals and ever-growing piety, and individuals might be filled with joy, peace, holiness, and ever-expanding and increasing love.
