As in verse 1 of the chapter, it appears that the apostle is responding to specific questions which the Corinthians have asked him. The question which prompted his response in this chapter may have been something like this: ‘Is it right or wrong to eat food offered up to idols?’ because in the open markets, food would be sold, much of which would have been offered up to idols.
We do not know the half of what we should know as Christians. We are learning all the time. Take, as an example, a promise of God. There are lots of Christians who know the promises of God, and yet they don’t really know them. Hebrews 13.5 gives us this promise: ‘Let your conversation be without covetousness; and be content with such things as ye have: for he hath said, I will never leave thee, nor forsake thee.’ You may say you know the promise, but if something happens to you which deeply disturbs you and you go to pieces, it proves you don’t know the promise. You don’t know a promise until you have proved it, that is to say, you have repeated it yourself, and you made it the basis of your faith and your prayer, and you have proved the goodness of God. Then you know it.
