The apostle Paul knew that there would be times when Timothy, as a minister of the gospel, would have to rebuke or correct others. However, Timothy was not to rebuke others on a whim. In fact, Paul specifically laid out two premises which Timothy’s rebuke should follow: “with all longsuffering and doctrine.” Timothy was to rebuke others while suffering with them for a long time, thus longsuffering. He was to exhibit grace by offering others the opportunity to rectify their areas of failure. At the same time, he was to rebuke others with sound doctrine and not simply based upon mere opinion. This was going to be even more necessary as some would begin to depart from sound doctrine and practice (2 Timothy 4:3-4).
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.
