Elder brothers obey God to get things. They don't obey God to get God himself — in order to resemble him, love him, know him, and delight him.
Timothy KellerGod's Kingdom is "present in its beginnings, but still future in its fullness. This guards us from an under-realized eschatology (expecting no change now) and an over-realized eschatology (expecting all change now).
