2 Corinthians 8:3
For I testify that they gave as much as they were able, and even beyond their ability — Paul himself witnesses (*martýreō*) to their giving, making the apostle an attestor to grace rather than a mere administrator. Their giving exceeds rational capacity: they give *hyper tēn dýnamin*, beyond their power, revealing that grace breaks the constraints of mere human ability. This voluntary self-transcendence points toward the Incarnation itself.
