Your kingdom come. This prayer points in two directions. The present and future. The present can be carried into effect when people treat each other with love, the future kingdom is what we hope for in eternity.
In God´s future kingdom we shall all be judged for what we have done. And more so for what we did not do.
Too often we set ourselves first, and set up our own kingdom on earth, and sprain our lives in the process.
Therefore we must incessantly pray: Your kingdom come.
