Not much different from today. We must prove our competition wrong, even if to do so we must become petty, picking on small differences. How easy it is to sit back and tear down the work of others, but how difficult to accomplish much ourselves. We must be sure we are producing life, not death, hope rather than despair, and operating in love, rather than a fault-finding spirit. Some things are obviously wrong, but other things are just petty foolishness.
Correction brings life and improvement, and correct discernment results in growth and progress.
Both must be motivated by love for the Lord, His people, even those operating in error. But this is not the way a complaining, negative spirit works. It never bears lasting fruit. It is more fueled by self-righteousness than by compassion and truth. Let's take up our cross and put down our critical attitudes.
