In Philippians, Paul refers to himself as a bond-servant (slave). The difference between being a slave of Christ and a servant of Christ is control. Servants can choose how they wish to serve, but a slave cannot for he/she is owned by God. The word slave denotes that there is a Master. Psalm 24 tells us that everything and everyone belongs to God. Brother Mike expounds on this idea of slave vs. servant and God’s ownership of all things. Philippians 1:1; Psalm 24:1 (NKJV)
