A world famous preacher likes to say that Jesus did “three day’s work” and that is all he ever did. By this, he means that he died, spent time in a tomb, and then rose to Heaven. That, to him, was all Jesus was good for.
But this ignores the mission of Jesus: to teach and preach. Jesus’ words, in the view of that minister, mean nothing.
But we cannot ignore Jesus' words, because Jesus said his words and teachings would last forever. Anyone teaching people to disregard his teachings, therefore, is misleading us.
Jesus said that to hear and follow his words is like building a house on solid rock (Luke 6:48) and whoever is ashamed of him and his words is the one Jesus will be ashamed of (Mark 8:38.)
He said to the Apostles at one point, "You don't also want to go away, do you?" Peter answered him, "Lord, to whom would we go? You have the words of eternal life." (John 6:67-68.)
Peter was right. Where, indeed, and to WHOM would we get better information about eternal life and salvation from sin than Jesus himself? There is no one other than Jesus we need to hear when it comes to this important subject.
The words of Jesus have no expiration date.
Jesus never said that his teachings and words to the Apostles were directed only to those living in Roman Judea. Instead, he says, "Heaven and earth will pass away, but my words will not pass away." (Matt. 24:35) While he did address certain things to his fellow Jews alone, his message and moral teachings are universal. Jesus never told us his words were only meant for a certain time in history.
There are no better teachings than the words of Jesus himself.
Jesus didn't say that after his ministry ended, someone else would be coming to interpret his words or change his teachings. Jesus said, “EVERYTHING that I learned from my Father, I have MADE KNOWN to you." Matt. 15:15. No further revelations are required for us to “learn” about God and God’s Will for our lives.
Jesus spoke on God's authority.
Jesus' words, he said, were not spoken on his own authority, but on God's (John 14:10) and Jesus said his actions always pleased God (John 8:29) making him our perfect example in all things.
If we believe this, then Jesus' words and actions reflect the Will of God, Who chose and anointed Jesus as God's spokesman, sending him out to preach a Good and Beneficial Message ("Gospel".) (Luke 4:18)
There is nothing greater, then, than the teachings of Jesus. They are to be the focus of our lives.
An often overlooked phrase in a popular verse, Jesus calls on us to teach and make disciples of all nations, and also, "teaching them to observe all things that I commanded you." All of his teachings, therefore, have eternal and profound significance, and deserve to be known by all peoples.
His clear teachings, therefore, calling us to perform Good Works, to seek heavenly treasures rather than earthly ones, to pray and act righteously without doing so just to be seen by others, to actively serve others, especially the poor, to turn the other cheek, to love and pray for enemies, and to go the extra mile in all that we do, HAVE NEVER BEEN CHANGED. Nor can we explain them away or minimize their importance, or allow others to do so.
Jesus' words have not been altered. His teachings remain in effect today. And his words were spoken in order to be followed by those who claim to love him.
