What does 1 Samuel 3 reveal about what God does in my place and on my behalf (the work of the Son)? God sends a chief prophet who perfectly reveals to us who God is. Being fully God and fully man, Jesus reveals the Father to us in his words and deeds. Because Jesus is both God and man, he can also intercede on our behalf, making atonement for sin.
1 Now the boy Samuel was ministering to the LORD in the presence of Eli. And the word of the LORD was rare in those days; there was no frequent vision.
