God, our Father, longs that we shall know and realize that we are His sons. He longs to hear us call Him Father from hearts that realize what they say, and that trust Him without a fear or anxiety. He is our Father, He alone in all the universe realizes the fullness of meaning that there is in that wonderful word “Father,” and it brings joy to Him to have us realize that He is our Father and to call Him so. Some years ago there was a father in the state of Illinois, who had a child who had been deaf and dumb from her birth. It was a sad day in that home when they came to realize that that little child was deaf and would never hear and, as they thought, would never speak. The father heard of an institution in Jacksonville, Ill., where deaf children were taught to talk. He took this little child to the institution and put her in charge of the superintendent. After the child had been there some time, the superintendent wrote telling the father that he would better come and visit his child. A day was appointed and the child was told that her father was coming. As the hour approached, she sat up in the window, watching the gate for her father to pass through. The moment he entered the gate she saw him, ran down the stairs and ran out on the lawn, met him, looked up into his face and lifted up her hands and said, “Papa.” When that father heard the dumb lips of his child speak for the first time and frame that sweet word “Papa,” such a throb of joy passed through his heart that he literally fell to the ground and rolled upon the grass in ecstasy. But there is a Father who loves as no earthly father, who longs to have His children realize that they are children, and when we look up into His face and from a heart which the Holy Spirit has filled with a sense of sonship call Him “Abba” (papa), “Father,” no language can describe the joy of God. CHAPTER XVI. THE HOLY SPIRIT AS A TEACHER. Our Lord Jesus in His last conversation with His disciples before His crucifixion said, “But the Comforter which is the Holy Ghost, whom the Father will send in My name, He shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you” (John xiv. 26). Here we have a twofold work of the Holy Spirit, teaching and bringing to remembrance the things which Christ had already taught. We will take them in the reverse order. I. _The Holy Spirit brings to remembrance the words of Christ._
