Jesus calls Levi/Matthew to follow Him. Matthew was a tax-collector. Tax-collectors were hated, both because they collected taxes, but were doing so for the Roman Empire. Tax-collectors who were also Jewish were considered traitors. Even so, Jesus calls Matthew to follow Him. Jesus calls people like you and me who others may not think worthy, but Jesus does so anyway. As a result Matthew gives a reception for Jesus with other tax-collectors and those the religious leader think to be sinners. Addressing their criticism, Jesus says that it is the sick that need a physician. Unstated, but true, when it comes to sin and being sinners, we all are in need of a physician and Jesus is the Great Physician. Churches and Christ followers should understand that we are in the dual position of being in need of a physician for our sins and are ones who are to assist leading people to Jesus and teaching them so that they are healed in more than their bodies, but their souls as well.
