True followers of Christ must be willing to follow his example of self-sacrifice. Like his Savior, Dr. King laid down his life by serving others. He once stated, "If a man hasn't discovered something that he will die for, he isn't fit to live." Laying down one's life does not necessarily require physical death; while we only die once, we should lay down our lives for others daily. However, we can only love others this way by walking in Christ's steps (1 Peter 2:21). He gave up the comfort and glory of heaven to bear the agony of unjust pain by embracing the cross and giving himself for humanity (Philippians 2:5-8).
Whenever the Bible calls on us to respond with an attitude or behavior that seems humanly impossible, we must ask the Lord to divinely enable us to do what we could never do without him. In fact, the whole walk of faith is one of going to God for the help we need that he alone can provide. It is only as Jesus fills us with his love that we can love others more like he does. God calls us unto liberty and exhorts us to freely choose by love to serve one another (Galatians 5:13). Those who would be great must first be servant of all, and those who so humble themselves shall be exalted (Matthew 23:11-12).
