Ambitions for God, if they are to be worthy, can never be modest. There is something inherently inappropriate about cherishing small ambitions for God. How can we ever be content that he should acquire just a little more honour in the world?
Christians should be eager to develop their gifts, widen their opportunities, extend their influence and be given promotion in their work — not now to boost their own ego or build their own empire, but rather through everything they do to bring glory to God.
