Back in Capernaum, some men bring to Jesus their paralytic friend on his bed. Jesus sees their faith and speaks comforting words of forgiveness to the man. When the scribes consider this blasphemy, Jesus sees their thoughts and corrects them. He uses His authoritative word to make the paralytic walk, and in so doing, He shows that His Word also has authority to forgive sins. The crowds rightly glo...

Jesus has commanded that He will go to the other side of the sea, and so He falls asleep in the boat as the disciples take Him across. The great storm that arises causes the disciples to forget the Lord’s promise, so they cry out to Him in fear. Jesus rebukes their fear before rebuking the winds and the sea. By this action, He clearly shows that He is God. On the other side of the sea, two demon-p...

When Jesus enters Peter’s house in Capernaum, He heals Peter’s mother-in-law, and she begins to serve Him. As Jesus continues His ministry of healing, He fulfills the promise of the Lord from Isaiah 53, bearing our sicknesses. When Jesus commands that He will be going to the other side of the Sea of Galilee, a scribe declares that he will follow Jesus wherever He goes. Jesus warns the man that to...

Having finished His teaching in the Sermon on the Mount, Jesus descends as crowds follow Him. A leper emerges and cries out for cleansing, which Jesus gives in His good will. In touching the leper, Jesus does not become unclean; instead, His cleansing flows to the leper. After Jesus enters Capernaum, a centurion approaches Jesus for healing for his servant. The centurion knows the authority of Jes...

Jesus concludes His Sermon on the Mount by urging those who have heard Him to put His Words into practice. This is what the poor in spirit do as they trust in Jesus to keep His promises. To have such faith is to build upon Jesus as a solid foundation; all other ground is sinking sand. Upon the conclusion of His Sermon, the crowds are amazed at Jesus’ authority. As the Gospel continues, that author...

False teaching would lead people off the narrow path to life. That’s why Jesus warns His disciples against the deception of false teachers. Although they may look good on the outside, their evil on the inside can be seen in the fruit of what they say. The Lord will not be fooled on the Last Day, however. False teachers do not truly know the Lord now, and they will depart from Him forever.   Rev. P...

Jesus reminds His disciples that they pray to their heavenly Father who is a generous Giver. They need not be afraid to ask, seek, or knock with confidence and persistence, because their heavenly Father knows even better than earthly fathers how to give good gifts. As God gives good gifts to His children, so Jesus’ disciples show love to others as they desire to be loved themselves. Though this wa...

Although Jesus does authorize His disciples to discern what is good from what is evil, Jesus does not authorize His disciples to bring the judgment of condemnation. That authority belongs to Him alone. Rather, with their eyes made healthy by the judgment of sin in Jesus’ cross, the disciples of Jesus can see clearly to help others see the forgiveness of sins found in Christ alone.  Rev. Harrison G...

Jesus teaches His disciples that trust in the true God instead of any idol brings freedom from worry. He invites His disciples to consider the simple examples of the way God cares for birds and flowers. If God loves such trivial things, He will surely love His dear children. Thus, the disciples are free to seek God’s kingdom and righteousness first, confident that God will give them all things nee...

Just as Jesus’ disciples do not practice their righteousness for the sake of being seen, so they do not treasure those things that can be seen. Rather, the true treasure of the Christian is a heavenly treasure, the righteousness of Christ that comes by faith. This treasure is indestructible and makes for a healthy eye, so that we can look upon the things of this life with the proper perspective. T...

Jesus expects that His disciples will engage in the discipline of fasting. Abstaining from food for a time reminds Christians that we do not live by bread alone, but by every Word that comes from the mouth of God. Like other forms of outward piety, Christians do not fast for the sake of being seen by others. Rather, the discipline of the flesh serves to benefit the Christian in deepening dependenc...

Just as Jesus expects His disciples will give to the needy, so He expects that they will pray. He warns against the prayer of the hypocrites, in which an outward show is the goal, and He also warns against the prayer of the Gentiles, in which prayer is heard by an abundance of words. Jesus instead grounds His disciples’ prayer in faith that their heavenly Father loves them, hears them, and already...

As Jesus teaches His disciples how to put His righteousness into practice, He warns them against doing it only for an outward show. They can have that reward, if they want, but then that temporal reward will be all they receive. Jesus expects that His disciples will practice their righteousness by giving to those in need. Such giving is not a matter of publicity, but a matter of showing mercy to t...

Jesus ensures that His disciples know that the neighbor whom they are to love includes their enemy. Their Heavenly Father pours His gifts upon the righteous and the unrighteous, and so His Christians are to show the same sort of perfect love. To love only those who love in return is to practice the sort of righteousness that even the pagans already accomplish. God calls His people to His own holin...

Jesus attacks any attempt to keep the Law as a matter of checking all the right boxes. Oaths are not a matter of using the right formulation. Instead, Jesus’ disciples should let their speech be saturated with the truth as they seek to keep the Second and Eighth Commandments. Even as God limited the retaliation of His people, He commends mercy to His people, as Jesus teaches His disciples to show...

As Jesus continues to expound upon His Law, He deepens our understanding of the Sixth Commandment. Physical adultery does not only break marriage; the lust of the heart already sins against God’s gift of a spouse. Jesus’ disciples shouldn’t just shrug their shoulders at divorce and make sure to go about it with the right procedures. Jesus’ disciples should keep their goal of upholding and protecti...

When Jesus states what His disciples have heard from the Old Testament, He does not contradict the Word of God but reveals the full depth of His truth. As Jesus begins to teach the true intention of the Fifth Commandment, He states that murder is more than an unlawful taking of life, but begins with anger, hatred, and insults. Rather than allowing anger to fester and grow in our hearts, Jesus teac...

Jesus prepares for a major section of teaching in His Sermon on the Mount by clarifying His relationship to the Scriptures. He has not come to abolish the Law or the Prophets, but to fulfill them. He will accomplish all that is written down to the smallest jot or tittle. Thus, none of Jesus’ disciples are free to relax God’s commandments in teaching or practice. Rather, Jesus calls His disciples t...

Having blessed His disciples, Jesus gives them an identity founded in Himself. His disciples are the salt of the earth, providing what is lacking in this world by bringing the Word of Jesus in word and deed. His disciples are the light of the world, not meant to be hidden but to be seen by all. Yet, the disciples of Jesus are not to be seen to draw attention to themselves. Their light is to reflec...

Jesus begins His Sermon on the Mount with nine beatitudes. Jesus speaks these statements of God’s blessing and salvation to unlikely groups, such as the poor in spirit, the mourners, and the persecuted Christians. Apart from their own merit or strength, they receive blessings from their heavenly King both now and in the future. By the end of this section, Jesus blesses not only “them,” but “you.”...

Even as a transitional text, these few verses reveal a great deal of the character of Jesus’ ministry. His teaching, proclaiming, and healing all bring His reign near as good news for sinners. Such ministry begins to draw crowds to Jesus from far and wide. Although not all the crowds come to saving faith in Christ, they still hear His teaching. As Jesus sits down to teach authoritatively, His disc...

John’s imprisonment foreshadows the suffering that Jesus will endure, but the time for His passion has not yet come. Jesus withdraws from Antipas’ territory and leaves His hometown Nazareth to adopt Capernaum as a home base. In so doing, Jesus fulfills the prophecy of Isaiah concerning the preaching of the Gospel in Galilee of the Gentiles. There, Jesus preaches the same sermon that John had preac...

After heaven opens to Jesus at His Baptism, hell now opens to attack Jesus at His temptation. Jesus goes into the wilderness and fasts for forty days, drawing strength from His Father. The devil tempts Jesus to satisfy His hunger with miraculous bread, but Jesus refuses to use His power for His own benefit. He defeats the devil with the written Word of God. When the devil attempts to twist the Scr...

When Jesus comes to John for the baptism that sinners have been receiving, John objects and says that Jesus ought to baptize him instead. Yet Jesus’ humility is fitting, for He has come to John’s baptism as the Lamb of God who takes away the sins of the world and fulfills all righteousness in the place of sinners. The theophany of the Triune God confirms the importance of Jesus’ Baptism, as the Sp...

St. Matthew introduces John the Baptist, moving the account of Jesus’ life forward to the cusp of His preaching ministry. John’s appearance in the wilderness fulfills God’s promise of the forerunner of the Christ, foretold by the prophet Isaiah. John’s clothing marks him as the Elijah who is to come, and his preaching and baptizing of repentant sinners prepares the way for Jesus’ ministry. John me...
