The Distinguishing Mark of Christianity
John MacArthur
Jesus is Lord (1 Corinthians 12:3) is the distinguishing article of Christianity and marks the essential confession of faith (Romans 10:9). Jesus proclaimed it to His disciples, His enemies, and His casual inquirers alike - and He refused to tone down its implications.
The expression "Lord" (kurios) speaks of ownership, while "Master/Lord" (despotes) denotes an unquestionable right to command (John 13:13; Jude 4). Both words describe a master with absolute dominion over someone else. That explains Jesus' incredulity at the practice of those who paid homage to Him with their lips but not with their lives: "Why do you call Me, 'Lord, Lord,' and do not do what I say?" (Luke 6:46).
Doulos frequently describes what it means to be a true Christian: "He who was called while free, is Christ's slave [doulos]. You were bought with a price" (1 Corinthians 7:22-23). It describes the lowest, abject bond slave; his service is not a matter of choice.
A Misleading Translation
Unfortunately, readers of the English Bible have long been shielded from the full force of doulos because of an ages-old tendency to translate it as "servant" or "bond-servant." This tendency is regrettable, since service and slavery are not the same thing. "No one can be a slave to two masters" (Matthew 6:24) makes better sense than "No one can serve two masters." An employee with two jobs could indeed serve two masters; but a slave could not. Scripture repeatedly calls Christians "slaves" (1 Corinthians 6:19-20), purchased for God (Revelation 5:9). This is the very essence of what it means to be a Christian (Romans 14:7-9).
A Revolting Concept
Not only is slave a word loaded with negative connotations, but our generation is also fixated on the concepts of freedom, fulfillment, and autonomy. Saving faith and Christian discipleship have been reduced to the cliché "a personal relationship with Jesus." It's hard to imagine a more disastrous twisting of what it means to be a Christian. Many people (including Judas and Satan) had some kind of "personal relationship" with Jesus during His earthly ministry without submitting to Him as Lord. But His only true friends were those who did what He said (John 15:14).
