In chapter 5:27-29 Luke records the story of Jesus calling Levi (Matthew) away from his tax booth. Levi answers the call by standing up, leaving everything, and following Jesus. What does it mean to “leave everything?” We may have heard guilt-trip type sermons on this before, always making us think we haven’t really “left all.” However, in the story, Luke tells us that after being called, Levi went home and threw a huge (and no doubt expensive!) party for a bunch of people (Jesus included). So what does it mean that Levi “left everything” if he still had a good size home and enough money to host a large feast? I appreciate Calvin’s words on this:
Luke 5:29. “And Levi made him a great banquet.” This appears to be at variance with what Luke relates, that he “left all”: but the solution is easy. Matthew [Levi] disregarded every hindrance, and gave up himself entirely to Christ, but yet did not abandon the charge of his own domestic affairs.
When Paul, referring to the example of soldiers, exhorts the ministers of the word to be free and disentangled from every hindrance, and to devote their labours to the church, he says: “No man that warreth entangleth himself with the affairs of life, that he may please the commander” (2 Tim. 2:4.) He certainly does not mean, that those who enroll themselves in the military profession divorce their wives, forsake their children, and entirely desert their homes; but that they quit their homes for a time, and leave behind them every care, that they may be wholly employed in war. In the same manner, nothing kept Matthew [Levi] from following where Christ called; and yet he freely used both his house and his property, as far as the nature of his calling allowed.
