This truth is a great mystery. Let it be enough to receive and believe it, and let us ever abstain from all attempts at explanation. It is childish folly to refuse assent to things that we do not understand. We are poor crawling worms of a day, and at our best, know little about God and eternity. Suffice it for us to receive the doctrine of the Trinity in Unity, with humility and reverence, and to ask no vain questions. Let us believe that no sinful soul could be saved without the work of all three Persons in the blessed Trinity, and let us rejoice that Father, Son, and Holy Spirit, who co-operated to make man, do always co-operate to save him. Here let us pause. We may receive practically what we cannot explain theoretically.
