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”?
The Bible admonishes believers to be stedfast and unmoveable (1 Corinthians 15:58). We are to be grounded and settled (Colossians 1:23) in the faith—much like a tree planted by the rivers of waters (Psalm 1:3). Yet, today's passage points to the dangers of a hardened heart set in rebellion. It is likened to a stone and a millstone. We should remain stedfast in our commitment to serve the Lord, yet our hearts should remain tender and pliable to Him and His will. A stony heart hinders the seed of God’s word from taking root (Matthew 13:5-6). This hardness hinders the possibility of spiritual fruit from taking root and maturing. A soft heart and a stedfast walk exhibit the godly balance that God desires for each of us.
