You would think it would be different. You would think that after a man by Grace uncovers the gift of salvation that he would go and sin no more, but that's not the case. In fact, it's the paradox of the human condition. God does not save us by giving us a clean slate by which we must keep clean in order to deserve that Mercy and remain saved. That is not the method by which we are saved. God puts the sin on Christ and puts the righteousness of Christ on us. Therefore, when God studies us, He does not see the man standing in his own righteousness nor does He see us for our eternal condition, but rather sees us in the righteousness of Christ.
I think that one of the tricks of Satan is for believers to study others in their own eternal condition and standing in their own righteousness instead of the Godly way of seeing others in the righteousness of Christ. This allows for no error, and when faults are found they stand out as witness against God. It's as if Satan is telling us "See! There is fault in this man who is saved. Therefore, there must be fault in his salvation!". Satan would have us believe there is no value in God's Grace and so no forgiveness. Therefore, we lose hope that our salvation is real - the power of Grace is diminished. We become consumed by either our own sin or disheartened by the sin of another.
This is why it is so important for us to understand ourselves and others in Christ as the unworthy saved by God's Grace and now clothed in the Righteousness of Christ. We remain unworthy but are forgiven! Can we do anything less for others?
