Eli was a priest and had a family with two sons. His response to grace was not good. Instead of correcting his two boys of perversion, he let them run wild and desecrate the temple and God. Eli's physical blindness was a indication of his spiritual blindness. Samuel heard God's voice and became a faithful servant. Samuel listened when God spoke. His response to God's grace was admirable and faithful to the very end.
What is your response to grace? Will you respond like Peninnah & Eli or like Eli & Samuel?
