God calls people into different works. In the midst of this diversity, a common thread unites all the work—men ought to do all they do to the glory of God.
Men tend to fret over the motives behind others’ actions. Instead, men should trust the Lord to deal with the motives at the judgment seat of Christ.
How would making your motive match the Lord's motive change how you approach the Christian life (from witnessing to praying to Bible reading and so on)?
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”?
