I cannot even remember the first time I read Genesis 1:3. Now I always have a general idea of what is going to come next. I have no idea how Moses would have felt or what he would have thought when, for the first time, God narrated to him “Then…” Moses must have been on the edge of his seat!
“Then God said ‘Let there be light’; and there was light.” (Genesis 1:3, NASB)
Here God brings light into existence out of nothing, no materials, no help. Before this, nothing like light existed. We find elsewhere that God created all of the heavens in this way (Psalm 33:6). Further, these created things are established firm and solid (Psalm 33:9). After God spoke, light leaped into existence.
Again, the text uses the name of God which means Almighty. The power of God is shown through His word. The word translated here as “said” is the Hebrew meaning God said this with His will – God decreed that light exist. The Hebrew word for light is the light of the morning or dawn – sunlight. Beyond obedience, light explodes into being.
Hebrews 11:3 states well that these things are understood by faith. God made everything without aid or material, by the power of His decree.
