All Knowing implies....

I agree with the teacher. Jesus gave it up to come and dwell with us as a man.

Mk. 13:
[30] Verily I say unto you, that this generation shall not pass, till all these things be done.
[31] Heaven and earth shall pass away: but my words shall not pass away.
[32] But of that day and that hour knoweth no man, no, not the angels which are in heaven, neither the Son, but the Father.
[33] Take ye heed, watch and pray: for ye know not when the time is.
[34]For the Son of man is as a man taking a far journey, who left his house, and gave authority to his servants, and to every man his work, and commanded the porter to watch.
[35] Watch ye therefore: for ye know not when the master of the house cometh, at even, or at midnight, or at the cockcrowing, or in the morning:
[36] Lest coming suddenly he find you sleeping.
[37] And what I say unto you I say unto all, Watch.
