An all knowing God...(but only propositionally)

[Fig-bearing Thistle]

I recently asked an Evangelical Christian this question regarding the Trinity:

So, you believe that the Trinity has all knowledge 'propositionally', but not all knowledge 'experientially'? Such as experienceing birth, mortality, sin, and death?

To which the person responded: Yes

I suppose all Trinitarians would agree with this: That the Trinity has always had all propositional knowledge, but little-to-no experiential knowledge with things such as creation, atonement, temptation, sin, death, mortality, etc.

Is this right?
