John 14:21-23 1 "He who has My commandments and keeps them, it is he who loves Me. And he who loves Me will be loved by My Father, and I will love him and manifest Myself to him." 22 Judas (not Iscariot) said to Him, "Lord, how is it that You will manifest Yourself to us, and not to the world?" 23 Jesus answered and said to him, "If anyone loves Me, he will keep My word; and My Father will love him, and We will come to him and make Our home with him.
In John 14 the Lord continues His "Farewell Discourse" (John 13-17). In this chapter He tells His disciples that He will be leaving them. For the disciples this causes a great deal of consternation. They have been with Him for three years and had grown very dependent upon Him in virtually every respect. In fact, His leaving was likened to the loss of parents, for in His assurances to His disciples He promises He will not leave them orphans (14:18).
However, what initially seems like bad news will actually turn out to be great news. His leaving them will not be permanent. First, He is going to prepare a dwelling place for them in heaven and then return to take them to be with Him. Second, He will be sending them Someone in His place Who is exactly like Him in every respect, the Holy Spirit (14:16-17). Not only will He be with them, but He will actually dwell in them! Third, both He (Jesus) and the Father will dwell in them as well! (John 14:23). This promises a kind of intimacy that is more meaningful for them than His being physically present with them!
(By the way this helps to explain the courage of the disciples in Acts as they boldly proclaimed Jesus before hostile audiences and were willing to die!).
I want to conclude by reviewing the concept of "dwelling." Consider that (1) Jesus prepares a "dwelling place" for us in heaven (the Father's house, 14:2-3), (2) the Holy Spirit will "dwell" within us (14:17). (3) the Father and the Son will "make their dwelling" within the believer (14:23). This great truth is expressed by a word group in Greek (noun and verb) that refers to "abiding, dwelling, remaining." The noun form is a dwelling place, the verb form means "to dwell." Jesus will return to this in John 15.
Take a moment and read this great old hymn (see link):
"No never alone, No never alone. He promised never to leave me, never to leave me alone." https://www.hymnal.net/en/hymn/h/688
Be encouraged by this great chapter in John!
