Integrity is something which must operate all the time. It is never relaxed.
We have started a new job perhaps, but integrity is asking already – will I have to work on Sunday? Will I be heading into something that I cannot do? I have this tremendous increase in pay, but what are the problems and the implications that later on I shall regret, because I shall have to lose integrity as a Christian by doing the wrong things? I will have to start making excuses and to start cutting worship and to leave off Christian duty. Then I will have to make all kinds of excuses for myself. A bit of foresight would have helped.
Or I am young, say, and I have got friends, and they ask me to come here and come there, and I accept every invitation, and I do not stop to think that means I will be back late five nights in a row, and I will have no devotions and I will not prepare my Sunday school lesson and I will have to skip my visiting. No, you see integrity does not want to be making excuses and covering up. Integrity looks ahead and says, I cannot do that. I measure my steps, I think ahead. Integrity looks ahead and it avoids trouble in advance.
We see that the first half of the proverb is singular and the second half is plural, which is discouraging really, because it suggests there is only one prudent person to every so many hundred naïve ones. That is not so clear in the English translation.
