Yes absolutely. To deny the personal or experiential realities of the Chistians faith would be erroneous. There are those aspects.
But what I'm saying is that Paul, who describes the gospel in great detail, never uses the language of "have a relationship with Jesus". He uses the concepts of law, accounting, transaction, exchange, imputation, business, etc.
If you want to be Biblical, if you want to express and communicate the gospel the way the apostles did, you won'tuse the language of "relationship".
If you are trying to deny logic and propositions, and relegate Christianity to existentialism, then you've denied the gospel altogether.
