Verse 1 And it came to pass The spiritual experience of Abraham was marked by four great crises, each of which involved a surrender of something naturally most dear. These were: (1) Country and kindred Genesis 12:1; Matthew 10:34-39; 2 Corinthians 6:14-18 (2) His nephew, Lot; especially dear to Abraham by nature, as a possible heir and as a fellow believer 2 Peter 2:7,8; Genesis 13:1-18. The completeness of Abraham's separation from one who, though a believer, was a "vessel unto dishonour," is shown by ; Genesis 15:1-3; 2 Timothy 2:20,21; Acts 15:36-40. (3) His own plan about Ishmael Genesis 17:17,18; 1 Chronicles 13:1-14; 15:1,2. (4) Isaac, "thy son, thine only son Isaac, whom thou lovest" Genesis 22:1-19; Hebrews 11:17,18. Verse 9 laid The typical lessons here are: (1) Isaac, type of Christ "obedient unto death" Philippians 2:5-8. (2) Abraham, type of the Father, who "spared not His own son, but delivered Him up for us all" John 3:16; Romans 8:32. (3) the ram, type of substitution--Christ offered as a burnt-offering in our stead, Hebrews 10:5-10. (4) cf. resurrection Hebrews 11:17-19; James 2:21-23.
