Oh Genesis 4, how hard it is to glean a promise from God out of you. I'm really sorry if this post seems a little contrived.
In Genesis 4, we see brother rise up against brother, quite literally. It's the famous chapter in which Cain kills Abel, on the account of jealousy. Then God comes into the spotlight and asks Cain where Abel is, and Cain of course denies any knowledge of his brother's whereabouts. But God doesn't need anybody to confess since He already knows everything anyway. Then we hear about Cain running off to the Land of Nod and building a city and naming it after his son Enoch. Then we go into a bit of genealogy, and from there there is not much more interesting news except that after Seth is born men begin to call upon the Lord.
Cain, after having killed his brother and then denied his knowledge, can't swallow his medicine. "And Cain said unto the LORD, My punishment is greater than I can bear." v 13. And so what do you think God does? Instead of forcing it down Cain's throat, He puts a mark on Cain's forehead so no one will kill him, and sends him out to the Land of Nod, where Cain can live out the rest of his life alive without fear of someone coming and avenging Abel's blood. And God even grants Cain a wife.
My friends, you can never get so bad as to wander beyond the reaches of the mercies of God. And if God can look out for Cain's life, Cain who killed his own brother in cold blood, how much more will your Heavenly Father forgive you if you come to Him.
P.S. These blogs will probably come out once to twice a week now. Every day was overkill, sorry. :P
