Matthew 6:10

His majesty, power and might, omnipresence, and omniscience having been confessed, the thought follows: Thy kingdom come. Thy will be done in earth as it is in heaven.

The kingdom of heaven, the sum total of the gifts and mercies of God in Jesus, which God has intended for all men and which is realized as the kingdom of grace in the believers, shall come. God must grant faith and keep us in faith and thus in His kingdom. John 15:1. But our prayer is also for others, that God may open their hearts and minds to the glorious news of their salvation by sending faithful pastors and missionaries, and that he would soon merge the Church militant into the Church triumphant. This petition implies that such is the good and gracious will of God. It follows, then, that this will of God should be perfectly, ideally done and fulfilled, and that all opposing forces should be broken and hindered. Incidentally, His will and allowance in our own lives should be carried out. Whatever of suffering and trials He is pleased to put upon us shall be borne willingly, since the angels themselves are models in the doing of God's will. At all times, in all places, in all things we pray that His will be done.
