Cain & Abel: Murder enters the world | Genesis

Anger and jealousy overtook Cain's heart, and pushed him to murder his
own brother Abel.
God called out to Cain much like he called out to Adam after his sin - but
Cain was not repentant or sorrowful.
Once more, sin brought death into the world - but Jesus still calls out to all
people, promising to forgive all who would turn from sin and follow Him.
