God spoke, and it was so. Gabriel told Mary, “With God, nothing will be impossible” (Luke 1:37), or literally from the Greek “No word of God is without power.” What did these words sound like when He spoke them? I don’t think He said them in English, or even in a language as we think of languages, but I bet that when He spoke it, there was a BIG BANG!!!
Jesus healed the sick in this same fashion. He merely spoke, “Be healed” and all were healed. He cast out devils with His word (Matthew 8:16).
The Book of Job seems to suggest that the angels were watching God’s creative activity with interest and were praising Him with great joy (Job 38:6‑7). Note the simplicity of this verse. There is no build‑up, no committee meeting, no magic words, no incantations. There was total darkness and blackness, and then God spoke simply and directly, “Let there be light.” And there was light, and it was good.
