If the iniquity which is in thine hand thou put far from thee, and wickedness dwell not in thy tabernacle, then shalt thou lift up thy face without spot, yea thou shalt be stedfast, and shalt not fear (Job 11:13-15).
Every sin is either committed in thought alone, or it is done in thought and deed together. Therefore ‘iniquity in the hand’ is offence in deed; but ‘wickedness in the tabernacle,’ is iniquity in the heart.
[…] Zophar…bids that ‘iniquity’ be removed from the ‘hand,’ and afterwards that ‘wickedness’ be cut off from the ‘tabernacle’.
For whosoever has already cut away from himself all wicked deeds without, must of necessity in returning to himself probe himself discreetly in the purpose of his heart, lest sin, which he no longer has in act, still hold out in thought.
[…] Now if we thoroughly wipe away these two, we then directly ‘lift our face without spot’ to God. For the soul is the inner face of man, by which same we are known, that we may be regarded with love by our Maker.
Now we are to lift up this same face, to raise the soul in God by appliance to the exercises of prayer. But there is a spot that pollutes the uplifted face, when consciousness of its own guilt accuses the mind intent; for it is forthwith dashed from all confidence of hope, if when busied in prayer it be stung with recollection of sin not yet subdued.
For it distrusts its being able to obtain what it longs for, in that it bears in mind its still refusing to do what it has heard from God.
Hence it is said by John, Beloved, if our heart condemn us not, then have we confidence toward God; and whatsoever we ask we shall receive of Him (1 John 3:21. 22). Hence Solomon saith, He that turneth away his ear from hearing the law, even his prayer shall be abomination (Prov. 28:9).
For our heart blames us in offering up our prayers, when it calls to mind that it is set in opposition to the precepts of Him, and…when there is a ‘turning away’ from the control of the law; in that verily it is meet that a man should be a stranger to the favours of Him, to Whose bidding he will not be subject.
Wherein there is this salutary remedy, if when the soul reproaches itself upon the remembrance of sin, it first bewail that in prayer, wherein it has gone wrong, that whereas the stain of offences is washed away by tears, in offering up our prayers the face of the heart may be viewed unspotted by our Maker.
