1 Corinthians 10:33

Even as I please all men in all things
The apostle sets himself as an example, though he was far from being a man pleaser, in the bad sense of that phrase; nor must these all things, in which he is said to please all men, be taken in the largest sense; but are to be understood of things indifferent, which might be done or avoided, without breaking the law of or contradicting the Gospel of Christ, or any of its rules and ordinances, to all which the apostle was inviolably attached; nor did he in these things seek to please men, but in all to act the part of a faithful servant of Christ, and steward of the mysteries of grace; see ( 1 Corinthians 9:19-22 ) . Moreover, it is not to bc thought that in fact he pleased all men; it is certain he did not; but he studied to please them; he did all that in him lay; he took the most proper methods to do it, though they were sometimes ineffectual.

Not seeking my own profit;
worldly profit and advantage, riches, wealth, the emoluments of life, ease, rest, and pleasure; and chiefly he means the use of liberty in things indifferent; he was willing to forego all for the good of others:

but the profit of many, that they may be saved;
he neglected his own private advantage, and the gratifying of himself in anything which was otherwise lawful, when he saw that would be an offence to others, be an hinderance of the Gospel, and deter any from embracing the Christian doctrine; that so he might be the, means of promoting the spiritual profit and edification of many souls, that they might be saved in the Lord with an everlasting salvation; He does not say all, but many, knowing that all will not be saved, only the elect of God; and whereas he knew not who these were, nor where they lay, he behaved in this manner to all men, that he might be the instrument of the spiritual good and salvation of the chosen ones among them, by preaching the Gospel to them without offence.
