I hoped to give you a start in answering the challenge to "explain Scripturally this whole business of 'relationship with Jesus'."

Here is another:

I am the true vine, and my Father is the husbandman. Every branch in me that beareth not fruit he taketh away: and every [branch] that beareth fruit, he purgeth it, that it may bring forth more fruit.

Now ye are clean through the word which I have spoken unto you.

Abide in me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; no more can ye, except ye abide in me.

I am the vine, ye [are] the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing. - John 15:1-5

Christ Jesus is our Life. We abide in Him and He abides in us. Without Him, we can do nothing.

In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God. All things were made by him; and without him was not any thing made that was made. In him was life; and the life was the light of men. – John 1:1-4

That is not a here v. there relationship. He indwells us.

But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his. - Romans 8:9

Notice also how the above verse affirms the Trinity - the Spirit, the Spirit of God, the Spirit of Christ.

Again,

What? know ye not that your body is the temple of the Holy Ghost [which is] in you, which ye have of God, and ye are not your own? - I Corinthians 6:19

For ye are dead, and your life is hid with Christ in God. – Colossians 3:3

To God be the glory, not man, never man.
