One of the things that we see in this story of Adam and Even and their children is that sin has consequences not just for the one that commits sin, but for all those around. Cain's sin affected his parents, his dead brother (obviously) and his own children.
That is one of the primary dangers of sin; it follows us around. One of the beliefs in our age that what is done in private has no affect on what happens in public. This story reminds us that it is not so. Every misdeed can affect people all around us.
New Testament Lesson
One of the neat things that the author of Hebrews does is that he lays out all the ways that Jesus is superior to all these other things and people. He is superior to angels, to Moses, to all the things. For, He is the one through whom salvation comes and He is the one through whom life flows.
Remember today, Jesus is above all and great than all. He is the one that we place our ultimate trust and faith, and He is the one to whom all praise is given.
Nathanael is to be commended in this text. He is able to move past his original conception of who Jesus was and see Him for who He really is. First he said, nothing good can come out of Nazareth. His original through was there was no way He could be the Messiah. But, when he met Jesus, he realized he was wrong, and followed.
Let us not be too hasty in making up our mind about someone before we know them. Nathanael did that, and it almost cost him. Thankfully he reconsidered and saw the truth. May we not rush to judgment, and when we find that we make a mistake, let us have the grace to admit it and amend our ways.
