Christians, from the Apostle Paul onwards, have always had the problem of trying to explain Jesus - especially what he did and why.
In other words the problem of trying to fit Jesus into a system.
We do this for not better reason than this is what we do; or for a host of 'bad' (or at least temporary, expedient) reasons to do with 'running society' - all of which seem to conflict with Jesus in some very fundamental, deeply-worrying sense.
But Jesus was a person, and when it comes to people (or at least, refers to any actual person whom we love) we don't try to fit them into a system that explains what they are 'really' doing, or what they are really 'for'. Rather, we recognise that persons come before systems; and systems are merely fitted-around people for secondary, temporary and expedient reasons - and these reasons are indeed often bad reasons; reasons that end-up with us regarding persons as mere cogs, subordinate-to and in-service-of the system.
The decision is stark - either we see Jesus as primary, or the systematic explanation of 'what Jesus did' as primary. And the proper answer ought to be obvious, once the matter has been lucidly stated.
The Gospel of John (my core source) gives us a Jesus who is a man, deep, utterly consistent yet absolutely unpredictable - judging each 'case' correctly, yet not according to system. A Jesus so unsystematic that he will not even reject the totality of a system (such as the Hebrew Law) because that would be merely to fall-into yet another system.
Jesus is fully divine, as well as a Man, hence he discerns, evaluates, judges from that divine self; above which nothing stands, because that divine self knows more than any system.
This is the nature of true judgement. It is not a means to an already-known end, neither is it subjective nor arbitrary - true judgement is a knowing of the reality of the situation, hence knowing what - specifically and exactly - should be done in this exact instance. And this true judgement is true morality.
Jesus is presented as exemplifying this - the example of Jesus is to show us the nature of correct discernment, true judgement, true morality (and not to provide us with yet-another-system to shackle, distort and usurp knowledge of the truth).
Jesus - across the gospel - is asking us to accept him, personally (not some system), as the primary reality, and the bottom line.
And knowing Jesus is not, never has been, an abstraction, because as well as God he is a person, an eternal person, who (since his resurrection and ascension) remains always in-this-world as well as 'not of this world'.
And we can know a person. A person is something we can know.
