We were weak, fallible, proud and full of sin even before disability entered our family. How can anyone hope to endure for a day, let alone ‘to the end’?
We trust in the New Covenant promises of sustaining, enabling grace that were obtained for us infallibly and irrevocably by Jesus Christ in his death and resurrection. Therefore our fight and our race and endurance is a radically God-centered, Christ-exalting, Spirit-dependent, promise-supported life. It is not a “just do it” ethic. It is not a moral self-improvement program. It is not a “Judeo-Christian ethic” shared by a vaguely spiritual culture with a fading biblical memory. It is a deeply cross-embracing life that knows the Christ of the Bible as the Son of God who was crucified first as our substitute and then as our model of endurance.
