There are two spirits as possibilities that we might do the will of. The god of this world, or the spirit of air. And the Spirit of Christ, the Holy Spirit of God. Those led by the Spirit of God are sons of God .While those led by the spirit of this world as natural unconverted men are considered children of the devil or Satan. No limbo in between
Eph 2:2 Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience:
Man is not created as a free agent but was designed to do the will of another .
To subject oneself in respect to spirits or gods (the unseen) is to violate the first commandments in so much as we are to have no other gods before our one God and savior. To deny Him is to blaspheme his Holy name as a authority by which we can believe. To Blaspheme that seen as the Son of Man was forgivable .Every time Peter denied Christ in unbelief (no faith) he violated the first commandment and did blaspheme the name of God.
'Giving' over authority to another does necessitate repudiating one's own authority, as usurping authority does 'take' it from another.
Then Peter took him, and began to rebuke him, saying, Be it far from thee, Lord: this shall not be unto thee.But he turned, and said unto Peter, Get thee behind me, Satan: thou art an offence unto me: for thou savourest not the "things that be of God", but "those that be of men". Mat 16:22
There must be a distinct difference between the things of God and those of men .Its where the prince of the air gets his foot in the door.
When Christ left he left clear instruction that although some did know him in respect to the temporal flesh as that seen .When he left we lose the temporal privilege and know him no more that way. Today blasphemy will not be forgiven if men have the faith of Christ, in respect to any man seen.
There is no temporal cushion called a daysman .a fleshly being set between God and man as some sort of infalible umpire (like a Pope) . God is not a man as us .never was never could be.
2Co 5:16 Wherefore henceforth know we no man after the flesh: yea, though we have known Christ after the flesh, yet now henceforth know we him no more.
Verily I say unto you, All sins shall be forgiven unto the sons of men,(the Son of man) and blasphemies wherewith soever they shall blaspheme:But he that shall blaspheme against the Holy Ghost (not seen)hath never forgiveness, but is in danger of eternal damnation. Mark 3:28
