Albert Barnes on 1 Corinthians 10:33

Even as I, etc. Paul here proposes his own example as their guide. The example which he refers to is that which he had exhibited as described in this and the preceding chapters. His main object had been to please all men; i.e., not to alarm their prejudices, or needlessly to excite their opposition, (1Cor 10:19); also 1Cor 10:20-23", while he made known to them the truth, and sought their salvation. It is well when a minister can without ostentation appeal to his own example, and urge others to a life of self-denial and holiness, by his own manner of living, and by what he is himself in his daily walk and conversation.
