I'm sick of the phrase, "personal relationship with Jesus Christ". In its common usage it is redundant and nonsensical at the same time.
First, all relationships are a personal affair. Every relationship involves at least one party. That's kind of the definition of "relationship". The party of the first part has interaction with the party of the second part. If a human is involved that relationship is unique to that "person".
Second, everyone on the planet has a relationship with Jesus Christ. You can believe in Him. You can even talk to Him. If you read the New Testament, He will even speak to you. If you deny that there is anything special about the person Jesus of Nazareth, you still have a relationship. It's one of skepticism or denial, but its still a relationship.
"My personal relationship with Jesus Christ" is a meaningless bunch of verbiage. There are four basic kinds of personal relationships you can have with Jesus: 1. Believe in Him, 2. Uncertain or doubt his authenticity, 3. Deny Him, 4. Obey and worship Him as God. Those are the four choices. That's it.
When I hear the sometimes gushing phrase; "My personal relationship with Jesus Christ", its normally followed by utter nonsense. What the speaker wants to talk about is their feelings about Christ. That might have its place. I don't know. Normally what ensues is an emotionally charged bit of navel gazing through the lens of Sunday School.
Not much is communicated about Christ, beyond some emotional impressions the speaker may have. The whole conversation would be further along if they just said, "I feel good about Jesus". The believers could say "amen" and the non-believing could say, "that's nice". Everyone could go about their business with minimal interruption.
"I follow Jesus", is a much more meaningful phrase. If that was followed up with another statement about either the blessings or difficulties of doing that, then a genuine conversation might ensure. That would require the speaker to have something to talk about that was deeper than their feelings or impressions. Doing that might be hard. It might even require an actual working personal relationship with Jesus.
Let's replace "personal relationship with Jesus Christ" and all its variants, with "Yay Jesus" and be done with it.
