Charles H. Spurgeon on Psalms 143:12

I am thy servant. David the king professes himself one of God's pensioners. Paul, when he would blaze his coat of arms, and set forth his best heraldry, he doth not call himself Paul, an Hebrew of the Hebrews, or Paul of the tribe of Benjamin, but Paul "a servant of Christ": Ro 1:1. Theodosius thought it a greater dignity to be God's servant than to be an emperor. Christ Himself, who is equal with his Father, yet is not ashamed of the title servant: Isa 53:11. Every servant of God is a son, every subject a prince: it is more honour to serve God than to have kings to serve us: the angels in heaven are servants to the saints. —Thomas Watson.
