Thinking of “others” in an abstract sense only is insufficient; we must get down to the nitty-gritty of true service. A famous philosopher wrote glowing words about educating children but abandoned his own. It was easy for him to love children in the abstract, but when it came down to practice, that was something else. Jesus thought of others and became a servant! Paul traces the steps in the humiliation of Christ: (1) He emptied Himself, laying aside the independent use of His own attributes as God; (2) He permanently became a human, in a sinless physical body; (3) He used that body to be a servant; (4) He took that body to the cross and willingly died.
Have you noticed as you read the four Gospels that it is Jesus who serves others, not others who serve Jesus? He is at the beck and call of all kinds of people—fishermen, harlots, tax collectors, the sick, the sorrowing. “Even as the Son of man came not to be ministered unto, but to minister, and to give His life a ransom for many” (Matt. 20:28). In the Upper Room, when His disciples apparently refused to minister, Jesus arose, laid aside His outer garments, put on the long linen towel, and washed their feet! (John 13) He took the place of a menial slave! This was the submissive mind in action—and no wonder Jesus experienced such joy!
