Read Mark 8:27-38.
In his timeless devotional, My Utmost for His Highest, Oswald Chambers wrote this: “The ecclesiastical idea of a servant of God is not just Jesus Christ’s idea. His idea is that we serve Him by being the servants of other [people]. The real test of the saint is not preaching the gospel, but washing disciples’ feet, that is, doing the things that do not count in the actual estimate of [others] but count everything in the estimate of God. Jesus Christ’s idea of a New Testament saint [is] not one who proclaims the gospel merely, but one who becomes broken bread and poured out wine in the hands of Jesus Christ for other lives.”
