Cain was sitting there all day asking himself what he can do to feel better than his brother or what he could to feel better about himself by hurting his brother or maybe someone else. His mind was on his brother or neighbour all day long as to what he might do. His brother had no idea. It is the craziest thing but Cain suffered Malice aforethought. Abel was the victim of an unlawful killing of another contrary to God's majestic peace and it all began with Cain killing one of Abel's old old sheep. It's just that Abel appreciated everything as if it was of God's hand. It had to be because He created everything and as such, Abel did not dissociate anything in his life from God. He would say the tree is God's tree and his loin cloth was God's loin cloth. Read Psalms 50 and Romans 8. It says that Enoch ascended into Heaven and so have you if you accept that the Kingdom of God is at hand and within you. Read John 1. Paul the apostle was right to say that we do not have an attitude as having already attained it but we press on toward the goal that is salvation in Christ. But certainly attitude determines altitude so live like it and your neighbour's new Billabong shoes won't bother you soo much or the other neighbour's used (but with some new polish) roof racks; racks get it?
