New Defender's Study Bible Notes
55:1 without money and without price. The grace of God in salvation is free, though the price paid by Christ was great.
55:3 sure mercies of David. This promise was quoted by Paul in his sermon at Antioch (Acts 13:34).
55:9 higher than the earth. This analogy, comparing the infinite thoughts of God to the very finite thoughts of man, would suggest that the heavens are infinitely higher than the earth. There is no end to space.
55:10 rain cometh down. Here is a beautiful anticipation and spiritual application of science’s hydrologic cycle. The rain and snow fall from the heavens and eventually return there, but not until they have done their providential work of watering the earth to provide and renew the world’s food supply. Analogously, God’s Word goes forth from heaven and yet is forever settled there (Psalm 119:89), returning after it has accomplished God’s spiritual work on earth.
55:11 not return unto me void. The fruitful spreading of God’s Word is presented in many Scriptures (e.g., Ecclesiastes 11:1,6; Matthew 13:8; I Corinthians 3:6-8; John 4:35-38).
55:13 instead of the thorn. The thorns were manifestations of God’s great curse on earth because of man’s sin (Genesis 3:17), but the curse will finally be forever removed (Revelation 22:3).
