Finney was reacting to the heresies of his time. People were adopting the easy-believism of name-it claim-it and other human fabrications. He also was seeking to correct the OSAS doctrine that men prefer to the truth. So Finney was anything but man-centered in his approach to issues such as justification.
Finney was lacking in the area of holiness. He was chiefly concerned with keeping away from wilfull sin and maintaining a constant vigil (watch and pray) against the eroding effects of a slack undervaluing of what we are actually doing.
He claimed that "disinterested benevolence" was a higher level than he knew....very honest of him. Of course "disinterested benevolence" is only possible when one is dead to oneself and abiding in Christ. THIS is holiness...to walk EXACTLY as Jesus through grace.
So he was not against this level of walk in Jesus. He was centering on the CONDITIONS by which we walk in a way approved of God. In other words he concentrated on OUR side of the relationship with God. The error he sought to correct is that so many claim that Jesus was obedient INSTEAD of them...thereby promoting a spoiled and sinful "saved" carnal man that destroys the gospel by denying the truth of the grace that transforms us into the very image of Christ.
