Cain and Abel explained

Amen to this (thank you Eric Richardson):
It is a teaching that we seek to unite the right wing and left wing as headwing; neither Abel nor Cain are right nor left wing. Abel is the person who is fundamentally closer to God.
It is Abel’s place to love Cain, but it is not Abel’s place to leave the position of being closer to God in order to appease Cain, make Cain feel better, make Cain feel tolerated, or make Cain feel loved by uniting with Cain. It is Cain’s position to unite with Abel and thereby do better and come closer to God.
It is also Abel’s responsibility to survive, and not be toppled from the position.
We sometimes hear that the killing of Abel is his fault because he did not love enough. Loving more is a good goal, but there is actually no real evidence that that was the case. Even if it were true, Abel can not make Cain commit the act of murder. This was all Cain’s doing.
God was clear that Cain was not right. He said, if you do not do well, will your offering not be accepted? It’s clear that Cain was not doing well, it was his fault and that it was not Abel’s fault that Cain did not succeed, but Abel did. It was Cain’s responsibility to figure out why, and change his offering. He could have asked Abel instead of becoming angry and resentful.
Without Abel, there is no chance for Cain to become better.
After Cain killed Abel, it was Cain’s descendants that created a world so full of evil that God grieved He ever created man.
Unity is Cain’s responsibility, not Abel’s.
