God is King...He Will Come as King

"The kingdom of God does not refer merely to a general or abstract concept of God’s sovereignty (God is king), but to his active, dynamic reign in history. God’s dynamic reign was evident even before the fall when God was busy expanding his blessing— bringing dominion over all the earth through his image bearers (Gen 1: 26– 28; 2: 15; cf. Psalm 8). ….Therefore, the message of the kingdom [after the Fall, and as the Bible unfolds] is not simply that God is king, but that God will come as king and set right what human sin has made wrong."
