Well, I would disagree with you. God is indeed calling all men NOW.
Could you go into detail and explain exactly what you mean when you say God is not calling people now please?
Let me start with the Priesthood of God; this is really quite a hidden message in scripture. But let me start with a few pieces.
Pieces....
Gen 37:3 Now Israel loved Joseph more than all his children, because he was the son of his old age: and he made him a coat of many colours (Heb) Pieces).
KJV
Hebrew OT:6446
Pieces: pac (pas); from OT:6461; properly, the palm (of the hand) or sole (of the foot) [compare OT:6447]; by implication (plural) a long and sleeved tunic (perhaps simply a wide one; from the original sense of the root, i.e. of many breadths):
I like the thought of pieces more; you see it is line upon line, precept upon precept; here a little there a little that is how you find truth.
Today we have all kinds of religious clothing; Baptist clothing, Catholic clothing etc. pieces.
Priesthood.
The priesthood of scripture is something very foreign to many believers understanding; they are so caught up in their doctrines of damnations they do not see the glory.
Take note in the word Zion/Sion.
Obadiah 1:21 And saviours shall come up on mount Zion (the high places of Ruleship in the kingdom) to judge the mount of Esau (Flesh); and the kingdom shall be the LORD's.
Ex. 19:5-6: "And ye shall be unto Me A KINGDOM OF PRIESTS." The full text reads, "Now, therefore, if ye will obey My voice indeed, and keep My covenant, then ye shall be a peculiar treasure unto Me above all people: for all the earth is Mine: and ye shall be unto Me A KINGDOM OF PRIESTS, and an holy nation."
God’s intentions from the first was He desired a kingdom of Priest but the Children of Israel were not equipped for they did not have the Holy Spirit to lead them and guide them in all truth. So God called forth men like Moses and David as a type of the Priesthood to come. David was a perfect example of this royal Priesthood.
We could not think of a disobedient people being for God - "a peculiar treasure, a kingdom of priests, and an holy nation." The apostle Peter speaks of the saints as "children of obedience"; they are begotten of that nature, and characterized by it. He speaks of "being born again, not of corruptible seed, but of incorruptible, by the living and abiding Word of God" (I Pet. 1:14, 23). Man after the flesh is born of corruptible seed, but there is another generation born of incorruptible seed, who desire earnestly the pure milk of the Word, and then the strong meat of the Word, and who grow up into the measure of the stature of the fullness of the Christ by it. They become "a chosen race, a kingly priesthood, a holy nation, a people for a purpose" (I Pet. 2:9). Just what the Lord proposed in Exodus chapter 19.
Acts 15:16-18
16 After this I will return, and will build again the tabernacle of David, which is fallen down; and I will build again the ruins thereof, and I will set it up:
17 That the residue (remainder) of men might seek after the Lord, and all the Gentiles, upon whom my name is called, saith the Lord, who doeth all these things.
What is the Tabernacle of David?
Revelations 1:6 And hath made us kings and priests unto God and his Father; to him be glory and dominion for ever and ever. Amen.
I work afternoons so I cannot go into a lot of detail now.
