I think the whole "personal relationship" is, at some level, important.
We are not saved by being born into a Christian family.
We are not saved by being a good person.
We are not saved by being wealthy, by earthly success.
We are not saved by going to church.
We are not saved by being baptized.
etc.
According to the scriptures our justification by grace through faith is personal. Now, simply stating a personal relationship with Jesus is a bit trite, but it is a step in the correct direction.

Grace is not common.
