How long should we go on questioning about Krishna when all our acharyas have already accepted him?

From Lohith

when questions and answers about krisna already discussed in the upanishads ,,,,,,, do we still need to ask  question about understading krishna, instead of accepting nector of the githa as it is.

my question here is when all our acharyas who come under the parampara have already accepted and followed gita and we are still questioning to accept it,,,,, is this kind persuasion towards the krishna is write or wrong,,,, if it write then how long should we  question about krishna.
