2Cor 4:1 Therefore, since we have this ministry, as we have received mercy, we do not lose heart.
The gospel that saves is the gospel that keeps and it is rooted in the mercy of God and boundless abundance of grace. As we have received mercy or in another expression, that we have been mercifully supported in all our trials, we do not faint or lose heart. The comfort we have is that we have received what we did not deserve or earn, that is mercy and that mercy is freshly supplied every morning (Lam 3:22-23).
Tim Challies described mercy as “God acting patient. It is God extending patience to those who deserve to be punished,” He continues, “Mercy is not something God owes to us by definition mercy cannot be owed, but is something God extends in kindness and grace to those who do not deserve it.”
The servant of Christ must therefore never forget that he once needed and obtained mercy. As God’s mercies are new every morning, this truth will sustain him in many countless hours when his heart and flesh fail. His weapon is the truth that appeals to his conscience. Psa 73:25 -26 “25 Whom have I in heaven but You? And there is none upon earth that I desire besides You. 26 My flesh and my heart fail; But God is the strength of my heart and my portion forever.”
