The cost of faithful obedience does not negate the worthiness and value of Scripture’s commands. The difficulty or unpleasantness of a task does not mean that the task is unnecessary or a worthless pursuit.

Church discipline is hard, relationally taxing, and requires significant attention and energy from the church. This level of investment and cost was causing the Thessalonian church to grow weary, and some were surely tempted to give up or give in. In our day, many church members are weary from the excessive commitments they have made outside of the church. This leads them to be unprepared and with little tolerance or energy for the mental attention, emotional fortitude, and spiritual determination required for church discipline. Additionally, our culture places great importance on preserving the individual’s self-esteem, emotional stability, and autonomy. Any attempt to express judgment towards an individual is countercultural and generally rejected. The church is not immune to these cultural forces and is often tempted to compromise biblical fidelity for the sake of cultural acceptance.

In this passage, Paul pleads with the church to faithfully endure in church discipline, regardless of how difficult the task may be.

All relationships require some level of separation. Marriage requires "forsaking all others," citizenship requires "renouncing all other allegiances, and to be a child of God requires forsaking all other masters. Romans 10:9 declares that salvation comes from believing God raised Jesus from the dead and confessing Jesus as Lord. If Jesus is Lord of your life, you have forsaken all other lords and renounced all allegiance and fidelity to any other lord.

2 Corinthians 6:14-7:1 is not a passage that is hard to understand, but it is one that offends the one who seeks to be friends with Christ and the world. It has two commands. One is a prohibition, and the other is a response to the transformation of the gospel. Both commands call the saints of God to live according to the righteousness of God and put away all defilements of the world.
