What does the Bible say about being a servant versus a son?

In Galatians 4:6-7, Paul expresses that because believers are sons of God, they have received the Spirit of His Son, enabling them to cry out to God as their Father. This indicates a profound shift in identity from merely being a servant to being a cherished son and heir. While the role of a servant implies duty and obligation, being a son encompasses relationship and inheritance, highlighting the grace and intimacy afforded to believers through Jesus Christ. This theological distinction elevates the approach believers should have toward God, moving from a mindset of obligation to one of joyful fellowship.
