Through the life of King David we can learn to succeed through failure. For much of his life, David was a shining example. But in one season of Davids life, he committed the sins of adultery and murder; for a whole year, he tried to cover up his sin. His sins show us even godly people may give in to temptation if they are not careful. Davids life teaches us the important thing is how we respond when we fail.
Jesus begins by teaching His disciples eight attitudes called, the beatitudes, or blessed attitudes, because each one is introduced by the word blessed. Jesus is promising to bless the disciple who has each of these attitudes. This word blessed can actually mean happy, spiritually prosperous, or in a state of grace. Each attitude also includes a promise that describes the form in which this blessing will come into the life of that disciple.
The word mercy means unconditional love. When David writes in Psalm 23:6 that mercy will follow him all the days of his life, the word he uses for follow actually means pursue. Gods unconditional love will pursue David all of his life. This is the kind of love for others that we must have too, if we are to be like God.
Many people think Jesus was contradicting the Old Testament in these verses, but He was only confronting the teaching of the religious leaders. He was telling His disciples: Everything I am teaching you is found in the Word of God, but what I am teaching is in direct conflict with what your religious leaders have been teaching you.
The Sermon on the Mount is one of the key teachings of the Bible. Jesus preached this sermon on a mountaintop in Galilee when He challenged people who professed to be His disciples to be strategically placed between the love of God and the pain of the hurting people in the world. He challenged His disciples to partner with Him and be conduits of His love. He concluded His sermon with a call to commitment. It changed the lives of many who heard it.
