In reality, it is not the Puritan mind that is suffering from an over-realized eschatology, it is surely the two kingdoms theorists who suffer from an under-realized soteriology! Salvation is limited to personal salvation and does not have the kingdom of God in view for history.Mission of God, 385
We can no longer afford to be pious functional deists as Christians who regard God as no longer active in history to judge & bless nations in terms of obedience to the gospel & who, whilst speaking of biblical inspiration deny its material authority & application in the world.
The Kingdom of God is primarily an eschatological concept. The fundamental idea of the Kingdom in Scripture is not that of a restored theocratic kingdom of God in Christ - which is essentially a kingdom of Israel-, as the Premillenarians claim; neither is it a new social condition - the primary idea of the Kingdom of God in Scripture is that of the rule of God established and acknowledged in the hearts of sinners by the powerful regenerating influence of the Holy Spirit - a rule that is realized in principle on earth, but will not reach its culmination until the visible and glorious return of Jesus Christ.Systematic Theology, 568
According to the Scriptures, therefore, special revelation is a historic process, an organic system, a continuous divine activity directed to destroying the power of sin, to the building up of the kingdom of God, to the restoration of the Cosmos, to the summing up of all things in Christ.
If past history is any indication, a Two Kingdoms or non-political approach to gospel engagement will fail in future days of tribulation. And not only will it fail in extending Christ's kingdom, i twill also fail to keep the church faithful to GodDeep Discipleship, 183
Although most Neo-Calvinists uphold the idea of natural law, they view it as an insufficient means of properly ordering the world because of the darkening of man's heart and mind. And so we need God's word in every sphere, not only in the church.Deep Discipleship, 181
Today, however, Christians in the West are found to be on the whole passionless, passive and one fears, prayerless. Cultivating an ethos that encloses personal piety in a pietistic cocoon, they leave public affairs to go their own way and neither expect nor, for the most part, seek influence beyond their own Christian circle... [but] the Puritans labored for a holy England and New England -sensing that where privilege is neglected and unfaithfulness reigns, national judgement threatens.
Missiology is the study of the salvation activities of the Father, Son, and Holy Spirit throughout the world geared toward bringing the kingdom of God into existence. Seen in this perspective missiology is the study of the worldwide church's divine mandate to be ready to serve this God who is aiming his saving acts toward the world. In dependence on the Holy Spirit and by word and deed the church is to communicate the total gospel and the total divine law to all mankind.
The Two Kingdoms view, currently espoused and championed by David VanDrunen and Michael Horton, more greatly emphasizes the distinction between the sacred and the secular; Christ rules the redeemed church through Scripture, whereas God rules the created world through natural law, to which all people have access. In this view, each believer belongs to two kingdoms - the (common) kingdom of the world and the (spiritual) kingdom of Christ.
"Fear God" and you will have nothing else to fear.
Don't fear what the next day may bring. Don't fear other people. Don't fear violence and power, even when it comes to you personally and can rob you of your life. Don't fear the high and mighty in the world. Don't fear yourself. Don't fear your sins. All these fears will die. From all these fears you will be set free. For they are no longer there. But fear God and him alone. For he has the power over all the powers of this world. The whole world is in fear of God. He has power to give us life or to destroy us. All other powers are a mere game.Remembrance Sunday: Who and What is Babylon? in Dietrich Bonhoeffer Christmas Sermons (Grand Rapids, MI: Zondervan, 2005), 111
the Kingdom of God is the redemptive reign of God dynamically active to establish his rule among men, and that this Kingdom, which will appear as an apocalyptic act at the end of the age, has already come into human history in the person and mission of Jesus to overcome evil, to deliver men from its power, and to bring them into the blessings of God's reign.
