To be sure, Christians want to go much further than this and see people actually brought into God's kingdom through faith in Jesus Christ. At the same time, we should not be shy of maintaining that outside the circle of the kingdom righteousness is more pleasing to God than unrighteousness, justice than injustice, freedom than oppression, love than hate, peace than war. In order to seek first God's kingdom we must evangelize, since the kingdom spreads only as the gospel of Christ is preached, heard, believed and obeyed. Everybody is ambitious to be or to do something, often from early years. Childhood ambitions tend to follow certain stereotypes - e.g. to be a cowboy, astronaut or ballerina.
Adults have their own narrow stereotypes too - e.g. to be wealthy, famous or powerful.
But ultimately there are only two possible ambitions for human beings. But beneath and beyond all these there is a contrast more fundamental still. Ambitions for God, however, if they are to be worthy, can never be modest. There is something inherently inappropriate about cherishing small ambitions for God. Once we are clear that God is King, then we long to see him crowned with glory and honour, and accorded his true place, which is the supreme place.
