We are examining the Sermon on the Mount, divided into 21 sections.
Jesus the Messiah addresses the principle of faith here.
This therefore concerns faith, the trust that God meets material needs. Those who devote themselves to divine work do so at the expense of earnings from their own employment. This illustrates the preceding principle: one cannot serve God and Mammon simultaneously!
For the person serving God, Jesus the Messiah uses birds and lilies of the field as examples to show that God watches over his disciples. Aware of human nature, Jesus repeats three times that they should not worry and mentions worry once.
This way of life may seem unusual, but Jesus the Messiah assures us that a true disciple will never be in need (Psalms 37.25). Furthermore, Jesus the Messiah indicates here that worry reflects insufficient faith. He will repeatedly reproach his disciples for this (Matthew 8.26, Matthew 14.31, Matthew 16.8).
This principle directly follows the previous theme concerning money, and the message is clear: devote yourselves diligently to advancing God's kingdom. You will consequently not have to worry about your own needs, because God promises to meet them.
Jesus the Saviour leaves nothing unclear and resolutely addresses every implication of his disciples' commitment.
From now on, the disciple relies on faith and therefore no longer needs to worry about other matters. The disciple must focus solely on their work and leave their Teacher to take care of the rest.
Luke 12.22-34 addresses this theme at a different point in Jesus the Messiah's ministry. Clearly, the apostles must have questioned the Teacher at length and frequently on this subject, since from childhood they had been accustomed to meeting all their needs themselves and now had to entrust that responsibility to God.
This change represents a significant challenge that may cause anxiety.
