A few years ago a man came to the prayer centre where I work in great turmoil. He said “I invited Jesus into my heart 10 years ago and I think I meant it and I think I felt His presence. But I don’t feel His presence any more. I think I’ve finally quenched the Spirit through my sins and now He’s left me.”
The guy seemed to know his bible very well. So I said “Can you think of any verses that talk about 'inviting Jesus into your heart'?”
He thought and said “No, I don't think I can.” (I mean there is stuff about Jesus coming to live in us (e.g. John 14:17) but that's not really the same thing). So I said to him, "You know what is in the bible...?" We spoke of the High Priest’s clothing in Exodus 28 and 29.
"Take two onyx stones and engrave on them the names of the sons of Israel in the order of their birth--six names on one stone and the remaining six on the other. Engrave the names of the sons of Israel on the two stones the way a gem cutter engraves a seal. Then mount the stones in gold filigree settings and fasten them on the shoulder pieces of the ephod as memorial stones for the sons of Israel. Aaron is to bear the names on his shoulders as a memorial before the LORD...."Whenever Aaron enters the Holy Place, he will bear the names of the sons of Israel over his heart on the breastpiece of decision as a continuing memorial before the LORD. (Exodus 28:9-29)
"Here's the bottom line" I said “Christ, your High Priest has you on His heart. My feelings go up and down. Christ stays up – all the time. And you’ll only feel Him in your heart (sporadically) when you know you’re on His heart, forever."
The centre of the Christian life is not your personal relationship with God. The centre of the Christian life is Christ’s personal relationship with God. But the good news is - Christ includes you in His communion.
