Genesis 4:26b, ".......men began to call upon the name of the Lord....." What does that mean? How does the relationship change between God and humanity at this point? Before this sin changes the relationship between God and man, after this point man becomes so perverse that God wipes out humanity in the flood. What does 4:26 mean? Is it an important point in the God/human relationship? Thanks for your answers to what I'm sure is a pretty basic kind of a question.
