In John 1:1-13, the Apostle John introduces Jesus to the world as the pre-existent “Word of God”, and in 1 John 1:1, as the “Word of life”, whom the apostles “have heard…seen…touched” — as a man. John has also revealed to us that the Word was the life that was “the true Light which enlightens every [person]…“

But, 

11 “Unto his own he came and His own people did not receive Him.” 

But,

12 to all who did “receive him”, who believed in his name, he gave the right to become children of God, 13 who were born…of God.
John 1:11-13

Maybe these are the passages where we got the clue that Jesus was meant for us.

Maybe you first heard about Jesus as you sang “away in the manger”? Later, you might have memorized John 1:12 in Sunday school like I did, along with
John 3:16. Did these verses open the door to your heart that showed you that you can sing, “Yes, Jesus loves me”?

After you received Jesus, did you wonder as I did, whether it might not be such a free gift. I certainly was too “bad” to be worthy. If it would depend on me,
I haven’t even come close. How about you?

So, is the gift of the Spirit contingent upon our obedience and not really a gift? Or does the Spirit actually empower obedience, when we first receive the gift, the promise of eternal life, as he then continues to empower us as we submit to Jesus in faith? Read Galatians 3 to inform your belief:

Let me ask you only this: Did you receive the Spirit by works of the law or by hearing with faith?

Does he who supplies the Spirit to you and works miracles among you do so by works of the law, or by hearing with faith — just as Abraham “believed God, and it was counted to him as righteousness”? Gal 3:2, 5-6 ESV

In this passage, Paul confirms that when we receive Jesus (repent of our sins, believe in his substitutionary “gift” of forgiveness and accept him as our Lord),
we are baptized into Jesus’ death, burial and resurrection by his Holy Spirit.

For as many of you as were baptized into Christ have put on Christ. Galatians 3:27

Then we go on living in his Spirit as he abides in us.

The Holy Spirit is always actively involved in promoting the promise of the Gospel, convicting the world of unbelievers of our need for a savior.

“…. It is to your advantage that I go away; for if I do not go away, the Helper will not come to you; but if I depart, I will send Him to you. And when He has come [at Pentecost], He will convict the world of sin, and of righteousness, and of judgment: of sin, because they do not believe in Me; of righteousness, because I go to My Father and you see Me no more; of judgment, because the ruler of this world is judged. John 16:7-11  (Emphasis added.)

So when Jesus emphasizes righteousness, what does he teach us about why we are accepted by him?

Then they said to him, “What must we do, to be doing the works of God?” 29 Jesus answered them, “This is the work of God, that you believe in him whom he has sent.” John 6:29

During his farewell address to his disciples, Jesus shared how he will be our companion even when he is with the Father:

“If you love me, you will keep my commandments. And I will ask the Father, and he will give you another Helper to be with you forever, even the Spirit of truth, whom the world cannot receive, because it neither sees him nor knows him. You know him, for he dwells with you and will be in you.
18 “I will not leave you as orphans (comfortless); I will come to you.  John 14:15-18  (Emphasis added)

Judas saith unto him, not Iscariot, Lord, how is it that thou wilt manifest thyself unto us, and not unto the world?
Jesus answered and said unto him, If a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him.  John 14:22-23 KJV (Emphasis added)

So when Jesus said “[he] will come to [us]” (John 14:18), and “we will come unto him, and make our abode with him” (John 14:23): he is referring to abiding, through his Holy Spirit, in any who believe. And this is Christ in us:

“…to make the word of God fully known, 26 the mystery hidden for ages and generations but now revealed to his saints. 27 To whom God would make known the glorious riches of this mystery among the nations, who is Christ in you, the hope of the glory. See, Colossians 1:21-28 (Emphasis added.)

This mystery is revealed in us who believe. Meditate on the miracle of the Holy Spirit living in you, revealing Christ to those around you.
