The Father and the Holy Spirit

The Lord Jesus in His farewell address uses the word Father more times than it occurs elsewhere in the whole of the gospels. If you begin at John 13 and underline the word Father on to the end of chapter 17, you will be surprised to find how very frequently the word occurs.
When the earth passes through a part of her journey around the sun, she comes into a sphere bright with the constant darting of spots of light—the region of the shooting stars. They are there in great abundance, and not clustered together in any other part of its course. So this portion of John's Gospel is especially bright with the clustered frequency of the word "Father.”
The Lord is introducing "His own" to the Father who has given them to Him, and in chapter 17, He addresses the Father about them, committing them to the Father's care, since He cannot remain with them to shield them beneath His sheltering wing.
When it is the Son and the Father He simply says, "Father." When He commits the disciples to Him in the midst of evil, He says, "Holy Father," and when He casts a glance at the world that has refused Him, hated both Him and His Father, He says, "O righteous Father, the world hath not known Thee: but I have known Thee.”
Why not say "heavenly Father" here? Because in John's Gospel He is "the only begotten Son, [who] is in the bosom of the Father." Consequently He could say as incarnate, "The Son of man [who] is in heaven." It is the Son and the Father in John.
In Matthew it is Jehovah and Jesus. He presents Himself as Messiah according to the Old Testament prophecies. He was born King of the Jews in Bethlehem. So among the people in the land of Israel He says, "My Father, which is in heaven" (Matt. 10:32, 33), and "My heavenly Father." "Every plant, which My heavenly Father hath not planted, shall be rooted up." Matt. 15:13. Here we have distance and earth as His sphere—"the land of Israel"—all so different from "the Son of man [who] is in heaven" in John's Gospel.
In the latter we are not standing in the Jewish position of servant—at a distance, but, as believers in the Son, we are in Christ Jesus made nigh through the blood of Christ, for "through Him we both have access by one Spirit unto the Father." We have now the same position, as we have the same nature, as the glorified Son of man, and He has ascended to His God and Father, and by grace we who believe in Him are brought to God our Father in Christ where He is in the heavenlies. So, being in conscious relationship to the Father, the Spirit of adoption giving us a sense of His love, and our nearness to Him, being in the light, as God is in the light, in fellowship with the Father and His Son Jesus Christ, we do not say "heavenly Father," but simply, "Abba, Father.”
Being in the enjoyment of the filial relationship and being in the Spirit, to faith "in heavenly places in Christ," we are where the Father is. "Behold, what manner of love the Father hath bestowed upon us, that we should be called the [children] of God." "Beloved, now are we the [children] of God." In the presence of our God and the Father in Christ we could not say heavenly Father, as if there were all the distance from earth to heaven between us.
My children do not address me as at a distance, but simply say "Father," for they are with me under the same roof in this city. But if they were in a foreign land it would not be improper for one of them to write and use the name of the place in connection with the word "father." We have the "Spirit of adoption whereby we cry, Abba, Father.”
