I never once said that He was not the God of the living. For this He is indeed. But the saints are dead to us.

They no longer walk the earth. You say that when Jesus went and took the keys of death and hades that Gods Spirit was not with Him?
Psa 139:2 You know when I sit down and when I rise up; You understand my thought from afar.
Psa 139:3 You scrutinize my path and my lying down, And are intimately acquainted with all my ways.
Psa 139:4 Even before there is a word on my tongue, Behold, O LORD, You know it all.
Psa 139:5 You have enclosed me behind and before, And laid Your hand upon me.
Psa 139:6 Such knowledge is too wonderful for me; It is too high, I cannot attain to it.
Psa 139:7 Where can I go from Your Spirit? Or where can I flee from Your presence?
Psa 139:8 If I ascend to heaven, You are there; If I make my bed in Sheol, behold, You are there.
Psa 139:9 If I take the wings of the dawn, If I dwell in the remotest part of the sea,
Psa 139:10 Even there Your hand will lead me, And Your right hand will lay hold of me.
Psa 139:11 If I say, "Surely the darkness will overwhelm me, And the light around me will be night,"
Psa 139:12 Even the darkness is not dark to You, And the night is as bright as the day. Darkness and light are alike to You.
Again you avoid the question asked of you.....
Joh 1:1 In the beginning was the Word: and the Word was with God: and the Word was God.
Joh 1:2 The same was in the beginning with God.
Joh 1:3 All things were made by him: and without him was made nothing that was made.
Joh 1:4 In him was life: and the life was the light of men.
Joh 1:5 And the light shineth in darkness: and the darkness did not comprehend it.
Joh 1:6 There was a man sent from God, whose name was John.
Joh 1:7 This man came for a witness, to give testimony of the light, that all men might believe through him.
Joh 1:8 He was not the light, but was to give testimony of the light.
Joh 1:9 That was the true light, which enlighteneth every man that cometh into this world.
Joh 1:10 He was in the world: and the world was made by him: and the world knew him not.
Joh 1:11 He came unto his own: and his own received him not.
Joh 1:12 But as many as received him, he gave them power to be made the sons of God, to them that believe in his name.
Joh 1:13 Who are born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.
Joh 1:14
And the Word was made flesh and dwelt among us (and we saw his glory, the glory as it were of the only begotten of the Father), full of grace and truth.
Joh 1:15 John beareth witness of him and crieth out, saying: This was he of whom I spoke: He that shall come after me is preferred before me: because he was before me.
And the Word who is Christ was made Flesh .......................
There is your Manhood for you. In one chapter of the Bible it describes fully this aspect.
Joh 1:51 And he saith to him: Amen, amen, I say to you, you shall see the heaven opened and the angels of God ascending and descending upon the Son of man.
He is called the Son of Man for a reason in the Bible.
Now onto the Keys of Death and Hades .....
Mat 16:18 And I say to thee: That thou art Peter; and upon this rock I will build my church, and the gates of hell shall not prevail against it.
Mat 16:19 And I will give to thee the keys of the kingdom of heaven. And whatsoever thou shalt bind upon earth, it shall be bound also in heaven: and whatsoever thou shalt loose on earth, it shall be loosed also in heaven.
That is because His Church has the Keys to Heaven and therefore was promised that Hell would not prevail against them.
As to your quote from Psalms
Psa 91:9 Because thou, O Lord, art my hope: thou hast made the most High thy refuge.
Psa 91:10 There shall no evil come to thee: nor shall the scourge come near thy dwelling.
Psa 91:11
For he hath given his angels charge over thee; to keep thee in all thy ways.
Psa 91:12 In their hands they shall bear thee up: lest thou dash thy foot against a stone.
Mat 17:1 And after six days Jesus taketh unto him Peter and James, and John his brother, and bringeth them up into a high mountain apart:
Mat 17:2 And he was transfigured before them. And his face did shine as the sun: and his garments became white as snow.
Mat 17:3 And behold there appeared to them Moses and Elias talking with him.
God gave the Angels and others ability to do things in his stead all throughout scripture.... In the last passage Jesus is appearing to them as God and has with Him Moses and Elijah ...... Giving incredible credence to the fact that they are in fact alive in Heaven. And that when called upon can be helpful to us.
2Ch 32:33 And Ezechias slept with his fathers, and they buried him above the sepulchres of the sons of David: and all Juda,
and all the inhabitants of Jerusalem celebrated his funeral: and Manasses his son reigned in his stead.
Why do we celebrate someone's death anyway if they are already dead and therefore have no more significance to us? If they are truly dead to us then why do we do this for them after they have departed and not before they have departed? It is as you can see something that is traditionally scriptural to do and why do you think that is?
