*4:3 See Genesis 15:6.
†4:5 We work because we have been justified, not in order to be justified (Ephesians 2:10). See further James 2:21-23—a living faith does things.
‡4:8 See Psalm 32:1-2. The negative is emphasized.
§4:11 We non-Jews may wonder why Paul is spending so much time on the subject of circumcision, but to the Jews of that day it was BIG.
*4:12 The point is that physical circumcision is not enough; one must believe.
†4:13 Now what might ‘heir of the world’ mean? “In you all the families of the earth shall be blessed” (Genesis 12:3). Galatians 3:16 makes clear that the Seed, singular, refers to the Christ (Genesis 12:7 and 24:7). Psalm 2:7-8 also clearly refers to the Christ: “I will declare the decree: the Lord has said to Me, ‘You are My Son, today I have begotten You. Ask of Me, and I will give You the nations for your inheritance, and the ends of the earth for your possession.’ ” It might be argued that in some sense this is happening through the Church, Christ's body—in Matthew 5:13-14 the Christ called His disciples “the salt of the earth” and “the light of the world”. Paul states, “all things are yours… and you are Christ's… and Christ is God's” (1 Corinthians 3:21-23). But during the millennial Messianic Kingdom the whole world will obey the Christ, who will rule the nations with ‘a rod of iron’ (Revelation 19:15).
‡4:15 How can you cross a line that is not there? So until someone draws a line (law) there is no transgression.
§4:17 See Genesis 17:5.
*4:17 God can create just by speaking: if He says, “Let there be…”, there is.
†4:18 See Genesis 15:5.
‡4:19 Perhaps 3% of the Greek manuscripts (of objectively inferior quality) omit “not”, to be followed by NIV, NASB, TEV, LB, etc.—an inferior proceeding.
§4:19 Paul declares that Abraham had become impotent before begetting Isaac. That means that he had started slowing down long before, and no one would be more aware of that than Sarah. That may explain why she offered Hagar—she was aware of the Promise and Abraham needed a descendant.
*4:21 “Being fully convinced” is a basic ingredient in true faith.
†4:25 The grammatical construction is the same in both clauses: ‘because’, ‘because’. The resurrection was the proof that the Father had accepted the price paid for our justification. Thank you, Jesus!
