summary
Paul ties relentless ministry effort to a rock-solid hope in the living God. The Father has made salvation available to all, yet it is applied in its fullest, eternal sense only to those who place their trust in Christ. Knowing this, we gladly expend ourselves for the gospel, confident that our labor matters now and forever.
