Focus Text: Genesis 4:6-9

The Lord said to Cain, “Why are you angry, and why has your   countenance fallen? If you do well, will you not be accepted? And if you do   not do well, sin is lurking at the door; its desire is for you, but you must   master it.”

Cain said to his brother Abel, “Let us go out to the   field.” And when they were in the field, Cain rose up against his   brother Abel, and killed him. Then the Lord said to Cain, “Where is your brother Abel?” He said, “I do   not know; am I my brother’s keeper?”
