Here we have one of the call narratives.
Samuel, who has been dedicated to God from infancy and raised to serve God, hears God's voice and doesn't immediately recognize it.
Samuel needs Eli to help him interpret the voice of God.
I think there is a lesson for us there. We need the help of others to interpret God's call in our lives. It is one of the reasons that we gather in community, so that we can test what we hear with other believers and together discern what God is calling us to.
