As I was reading today, the event that got my attention was when Cain offered an inadequate sacrifice to God, which was rejected by God.
The scripture says that Cain was saddened, or upset because his sacrifice was rejected. God simply told him, "Is there not, if thou dost well, acceptance?" YLT. Then, "and if thou dost not well, at the opening a sin-offering is crouching, and unto thee its desire, and thou rulest over it."
So, God offered Cain an offering of the lamb that would forgive him for offering the wrong offering to God. God's love for all, including the rebellious is uncomprehensible. We know that Cain rejected God's provision and instead murdered his brother.
God's Lamb is standing at the door for everyone who sins. We can either accept or reject His provision. The results of rejection is not God's fault, it's only the consequences of our choice.
Choose the Lamb!
