As Jesus gets closer to Jerusalem he spends more and more time with the twelve. He is preparing them for their task. When he is gone, they must follow in his ways. And so Jesus explains that the one who would lead in his kingdom must imitate him.
All Christians are called servants of Christ ‚Äď therefore it is the calling of every Christian to serve one another. Every Christian man should aspire to being an elder ‚Äď the sort of man that other men in the church look up to as an example. Every Christian woman should aspire to being one of those older women whom Paul refers to in Titus 2 as a discipler of the younger women.
But if you would become such a person, you must start now. And you must start by denying yourself, taking up your cross, and following Jesus.
