New Defender's Study Bible Notes
3:4 For every house. By the universal scientific law of cause and effect, it is obvious that a house must have been “caused” by a builder of the house. But that builder must have been “caused” by his parents and his education, etc. And so on. Every effect must have a cause. But ultimately there must either be an infinite string of secondary causes (and what caused that?) or an uncaused First Cause. The latter is far more reasonable. Thus, the “Builder” of “all things is God!”
3:4 built all things. From Hebrews 3:3, it is evident that Christ is the builder of the cosmic house; from this verse, therefore, it follows that Christ is God. He is the one who created and made all things (Colossians 1:16; John 1:3).
