Sorry, I am crunching with work! I should have worded that differently as it is written from mans perspective...God didn't have to, He is omniscient, so He already knows everything, but most of us relate to and want someone around that knows and understands what we have gone through or where we are coming from...?
Inasmuch then as the children have partaken of flesh and blood, He Himself likewise shared in the same, that through death He might destroy him who had the power of death, that is, the devil, and release those who through fear of death were all their lifetime subject to bondage. For indeed He does not give aid to angels, but He does give aid to the seed of Abraham. Therefore, in all things He had to be made like [His] brethren, that He might be a merciful and faithful High Priest in things [pertaining] to God, to make propitiation for the sins of the people. For in that He Himself has suffered, being tempted, He is able to aid those who are tempted. Heb 2:14-18
