Every Christian should be both conservative and radical; conservative in preserving the faith and radical in applying it.
John StottIf we truly worship God, acknowledging and adoring his infinite worth, we find ourselves impelled to make him known to others, in order that they may worship him too. Thus worship leads to witness, and witness in its turn to worship, in a perpetual circle.
John StottThe nations are not gathered in automatically. If God has promised to bless "all the families of the earth," he has promised to do so "through Abraham's seed" (Genesis 12:3, 22:18). Now we are Abraham's seed by faith, and the earth's families will be blessed only if we go to them with the gospel. That is God's plain purpose.
