Listen to Blake and the Bible commenting on Jesus, Sin, Error, Forgiveness, Satan and Judgment. These quotes from the two sources allow us to compare New Testament concepts and how similar ideas appear in Blake:
CHRIST AS THE REDEEMER OF MAN
1)Jesus not the accuser (Satan) is our judge.
 My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous:
Vision of the Last Judgment, (E 565)
"Forgiveness of Sin is only at the Judgment Seat of Jesus the
Saviour where the Accuser is cast out. not because he Sins but
because he torments the Just & makes them do what he condemns as
Sin & what he knows is opposite to their own Identity"
2) The accuser has no power over us.
 And I heard a loud voice saying in heaven, Now is come salvation, and strength, and the kingdom of our God, and the power of his Christ: for the accuser of our brethren is cast down, which accused them before our God day and night.
Vision of the Last Judgment,(E 564)
as he came at first to deliver those who were bound under the
Knave not to deliver the Knave He Comes to Deliver Man the
[Forgiven] not Satan the Accuser we do not
find any where that Satan is Accused of Sin he is only accused of
Unbelief & thereby drawing Man into Sin that he may accuse him.
Such is the Last Judgment a Deliverance from Satans Accusation
Satan thinks that Sin is displeasing to God he ought to know that
Nothing is displeasing to God but Unbelief & Eating of the Tree
of Knowledge of Good & Evil"
3) The light of Truth leads us to the new creation.
 To open their eyes, and to turn them from darkness to light, and from the power of Satan unto God, that they may receive forgiveness of sins, and inheritance among them which are sanctified by faith that is in me. [PAUL]
Vision of the Last Judgment, (E 565)
"I will not Flatter them Error is
Created Truth is Eternal [,] Error or Creation will be Burned Up &
then & not till then Truth or Eternity will appear It is Burnt up
the Moment Men cease to behold it I assert for My self that I do
not behold the Outward Creation & that to me it is hindrance &
not Action it is as the Dirt upon my feet No part of Me."
4) Forgiveness of sins is God's will.
 And, behold, they brought to him a man sick of the palsy, lying on a bed: and Jesus seeing their faith said unto the sick of the palsy; Son, be of good cheer; thy sins be forgiven thee.
 For whether is easier, to say, Thy sins be forgiven thee; or to say, Arise, and walk?
 But that ye may know that the Son of man hath power on earth to forgive sins, (then saith he to the sick of the palsy,) Arise, take up thy bed, and go unto thine house.
Jerusalem, Plate 20, (E 165)
"Jerusalem answer'd with soft tears over the valleys.
O Vala what is Sin? that thou shudderest and weepest
At sight of thy once lov'd Jerusalem! What is Sin but a little
Error & fault that is soon forgiven; but mercy is not a Sin
Nor pity nor love nor kind forgiveness! O! if I have Sinned
Forgive & pity me! O! unfold thy Veil in mercy & love!
Slay not my little ones, beloved Virgin daughter of Babylon
Slay not my infant loves & graces, beautiful daughter of Moab"
5) The religion of Jesus practices mercy not vengeance.
 Woe unto you, scribes and Pharisees, hypocrites! for ye pay tithe of mint and anise and cummin, and have omitted the weightier matters of the law, judgment, mercy, and faith: these ought ye to have done, and not to leave the other undone.
Jerusalem, Plate 52, (E 201)
"Man must & will have Some Religion; if he has not the Religion
of Jesus, he will have the Religion of Satan, & will erect the
Synagogue of Satan. calling the Prince of this World, God; and
destroying all who do not worship Satan under the Name of God.
Will any one say: Where are those who worship Satan under the
Name of God! Where are they? Listen! Every Religion that Preaches
Vengeance for Sins the Religion of the Enemy & Avenger; and not
the Forgiver of Sin, and their God is Satan, Named by the Divine
Name Your Religion O Deists: Deism, is the Worship of the God
of this World by the means of what you call Natural Religion and
Natural Philosophy, and of Natural Morality or
Self-Righteousness, the Selfish Virtues of the Natural Heart.
This was the Religion of the Pharisees who murderd Jesus. Deism
is the same & ends in the same."
6) Practicing Forgiveness builds the Kingdom of God
 Then came Peter to him, and said, Lord, how oft shall my brother sin against me, and I forgive him? till seven times?
 Jesus saith unto him, I say not unto thee, Until seven times: but, Until seventy times seven.
Jerusalem, Plate 77, (E 232)
"And remember: He who despises & mocks a Mental Gift in another;
calling it pride & selfishness & sin; mocks Jesus the giver of
every Mental Gift, which always appear to the ignorance-loving
Hypocrite, as Sins. but that which is a Sin in the sight of cruel
Man, is not so in the sight of our kind God.
Let every Christian as much as in him lies engage himself
openly & publicly before all the World in some Mental pursuit for
the Building up of Jerusalem "
The influence that the Bible had on shaping the mind of Blake led him to become a religious poet. He used the Christian metaphors in unique ways but always with the goal of opening the minds of men to the 'perception of the Infinite'.
