There are issues in which believers will disagree. In such cases, we should understand that we will independently stand before the judgment seat of Christ.
At times, believers tend to get at odds with other believers. Instead, we should be thankful for our fellow believers and the benefits they bring to the body.
More knowledgeable Christians should never mock or disdain weaker believers, nor should they become stumblingstones toward these brethren.
The apostle Paul was troubled greatly by the behaviour of the Corinthian believers. Due to their carnality, he could not speak to them as he would mature believers (1 Corinthians 3:1). Not only was Paul troubled by their actions during his absence, but also feared their condition when they would again meet face-to-face. He warned the believers that he would not be pleased if he found them guilty of such sins. Among the other shortcomings, Paul expressly mentioned their backbiting ways. The hope was that the Corinthian believers would repent of these grievous sins and simply do right. These admonitions should make believers reflect on the fact that the Lord Jesus could also come at any moment. How would He find us? Would we too be guilty of “debates, envyings, wraths, strifes, backbitings, whisperings, swellings,” and “tumults”?
