Charles H. Spurgeon on Psalms 50:4

He shall call to the heavens from above, and to the earth. Angels and men, the upper and the lower worlds, are called to witness the solemn scene. The whole creation shall stand in court to testify to the solemnity and the truth of the divine pleading. Both earth beneath and heaven above shall unite in condemning sin; the guilty shall have no appeal, though all are summoned that they may appeal if they dare. Both angels and men have seen the guilt of mankind and the goodness of the Lord, they shall therefore confess the justice of the divine utterance, and say "Amen" to the sentence of the supreme Judge. Alas, ye despisers! What will ye do and to whom will ye fly? That he may judge his people. Judgment begins at the house of God. The trial of the visible people of God will be a most awful ceremonial. He will thoroughly purge his floor. He will discern between his nominal and his real people, and that in open court, the whole universe looking on. My soul, when this actually takes place, how will it fare with thee? Canst thou endure the day of his coming?
