Adam slept with Eve his wife. She conceived and had Cain. She said, “I’ve gotten a man, with God’s help!”
Then she had another baby, Abel. Abel was a herdsman and Cain a farmer. Time passed. Cain brought an offering to God from the produce of his farm. Abel also brought an offering, but from the firstborn animals of his herd, choice cuts of meat.
God liked Abel and his offering, but Cain and his offering didn’t get his approval. Cain lost his temper and went into a sulk. God spoke to Cain: “Why this tantrum? Why the sulking? If you do well, won’t you be accepted? And if you don’t do well, sin is lying in wait for you, ready to pounce; it’s out to get you, you’ve got to master it.”
Genesis 4 : 1 -7 (The Message)
“When Cain was born, Eve said, I have gotten a man from the Lord. Perhaps she thought that this was the promised seed.
If so, she was wofully disappointed. Abel signifies vanity: when she thought she had the promised seed in Cain, whose name signifies possession, she was so taken up with him that another son was as vanity to her. Observe, each son had a calling.
It is the will of God for every one to have something to do in this world. Parents ought to bring up their children to work. Give them a Bible and a calling, said good Mr. Dod, and God be with them. We may believe that God commanded Adam, after the fall, to shed the blood of innocent animals, and after their death to burn part or the whole of their bodies by fire.
Thus that punishment which sinners deserve, even the death of the body, and the wrath of God, of which fire is a well-known emblem, and also the sufferings of Christ, were prefigured. “#
