John portrays Jesus repeatedly saying that his words come directly from God.
“My teaching is not mine but his who sent me.” (John 7:16)
“…the one who sent me is true, and I declare to the world what I have heard from him.” (John 8:26)
“for I have not spoken on my own, but the Father who sent me has himself given me a commandment about what to say and what to speak. And I know that his commandment is eternal life. What I speak, therefore, I speak just as the Father has told me.” (John 12:49-50)
“Do you not believe that I am in the Father and the Father is in me? The words that I say to you I do not speak on my own; but the Father who dwells in me does his work.”(John 14:10)
“…the word you hear is not mine but is from the Father who sent me.” (John 14:24)
“For I gave them (the disciples) the words you gave me and they accepted them.” (John 17:8)
So, Jesus said, clearly, that his words come directly from his father, God. But Jesus doesn’t just want us to listen to the words given to him by his father. He wants us to act on them.
“You are my friends if you do what I command you.” (John. 15:14)
“My mother and my brothers are those who hear the word of God and do it.” (Luke 8:21; Matthew 12:50; Mark 3:35)
“Blessed …are those who hear the word of God and obey it!” (Luke 11:28)
“I will show you what someone is like who comes to me, hears my words, and acts on them. That one is like a man building a house, who dug deeply and laid the foundation on rock; when a flood arose, the river burst against that house but could not shake it, because it had been well built. But the one who hears, and does not act, is like a man who built a house on the ground without a foundation. When the river burst against it, immediately it fell, and great was the ruin of that house.” (Luke 6:47-49)
Jesus also tells us that if we love him we will obey his teaching.
“Anyone who loves me will obey my teaching. My Father will love them, and we will come to them and make our home with them.
Anyone who does not love me will not obey my teaching. These words you hear are not my own; they belong to the Father who sent me.” (John 14:23-24)
The Greek in this verse is not completely clear. Is this a command? Is Jesus saying that anyone who loves him must make sure that they obey his teaching? Probably not. What Jesus seems to be saying is that anyone who truly loves him will find themselves obeying his teaching. The clue comes in the next few verses.
“All this I have spoken while still with you. But the Advocate, the Holy Spirit, whom the Father will send in my name, will teach you all things and will remind you of everything I have said to you. Peace I leave with you; my peace I give you. I do not give to you as the world gives. Do not let your hearts be troubled and do not be afraid.” (John 14:24-27)
Jesus had already spoken to his disciples about the “Spirit of Truth”that would be given to them by his Father. This Spirit of Truth, the Holy Spirit, would be “another counselor” who would take the place of Jesus in the lives of his disciples. (John 14:15-17)
Finally, Jesus said that his words are spirit and life and they will never pass away.
“It is the spirit that gives life; the flesh is useless. The words that I have spoken to you are spirit and life.” (John 6:63)
“Heaven and earth will pass away, but my words will never pass away.” (Matt 24:35; Mark 13:31; Luke 21:33)
