Then you have a comprehensive description of what "by me" looks like?
Two, two letter words...How comprehensive can it get??? You can't get to the Father unless you go thru the Son...
Mat 11:27 All things are delivered unto me of my Father: and no man knoweth the Son, but the Father; neither knoweth any man the Father, save the Son, and he to whomsoever the Son will reveal him.
I realize that's not your argument tho...Your argument is that you need (or desire) a mediator between you and Jesus...Problem is, you have no idea whether your mediator has contact with Jesus...
Be a pity to have someone mediate and not have your petitions make it to God...
But I wouldn't waste 10 seconds asking Mary or a 'saint' to mediate between Jesus and me...And here's why...
Heb 4:13 Neither is there any creature that is not manifest in his sight: but all things are naked and opened unto the eyes of him with whom we have to do.
Heb 4:14 Seeing then that we have a great high priest, that is passed into the heavens, Jesus the Son of God, let us hold fast our profession.
Heb 4:15 For we have not a high priest which cannot be touched with the feeling of our infirmities; but was in all points tempted like as we are, yet without sin.
Heb 4:16 Let us therefore come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need.
This doesn't require a comprehensive description either...You can take your petitions right to the One who can grant your petitions...And you do it boldly...
Mat 11:28 Come unto me, all ye that labor and are heavy laden, and I will give you rest.
Mat 11:29 Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls.
Mat 11:30 For my yoke is easy, and my burden is light.
