perfection(-ness)

Dictionary of Biblical Words:

Absolute perfection is in Christ alone. However, the Christian may be kept from sinning by dependence on Christ and constant watchfulness, the root of sin is ever in him, ready to show itself at every unguarded moment. Besides, it is ever true that in many things we all offend. All this does not excuse us for sinning, which is always caused by our own self will or carelessness.
