John Gill emphasizes that suffering for righteousness, particularly for the sake of Christ and His Gospel, is an expected part of the Christian life. He explains that such suffering, while painful, is a mark of honor and a gift from God, as it strengthens faith and glorifies God. Gill reassures believers that despite persecution, they remain blessed and are comforted by the presence of the Holy Spirit. He encourages Christians not to fear the threats or reproaches of the world, as God is their protector and love casts out fear. Ultimately, the promise of eternal glory far outweighs any temporary suffering they may endure.
