30.  And not only Paul, but generally all those to whom is committed any ministry of the word, never cease from testifying, but call heaven and earth to witness on the ground that now every deed that is done is done within them, and that in the examination of all the actions of life they will be present with the judged.  So it is said, “He shall call to the heavens above and to earth, that he may judge his people.” Ps. l. 4.  And so Moses when about to deliver his oracles to the people says, “I call heaven and earth to witness this day;” Deut. iv. 26. and again in his song he says, “Give ear, O ye heavens, and I will speak, and hear, O earth, the words of my mouth;” Deut. xxxii. 1. and Isaiah, “Hear, O heavens, and give ear, O earth;” Isa. i. 2. and Jeremiah describes astonishment in heaven at the tidings of the unholy deeds of the people:  “The heaven was astonished at this, and was horribly afraid, because my people committed two evils.” Jer. ii. 12, 13, lxx.  And so the apostle, knowing the angels to be set over men as tutors and guardians, calls them to witness.  Moreover, Joshua, the son of Nun, even set up a stone as witness of his words (already a heap somewhere had been called a witness by Jacob), Gen. xxxi. 47. for he says, “Behold this stone shall be a witness unto you this day to the end of days, when ye lie to the Lord our God,” Josh. xxiv. 27, lxx. perhaps believing that by God’s power even the stones would speak to the conviction of the transgressors; or, if not, that at least each man’s conscience would be wounded by the force of the reminder.  In this manner they who have been entrusted with the stewardship of souls provide witnesses, whatever they may be, so as to produce them at some future day.  But the Spirit is ranked together with God, not on account of the emergency of the moment, but on account of the natural fellowship; is not dragged in by us, but invited by the Lord.
