"There is also a perfection of degrees, by which a person performs all the commands of God, with the full exertion of all his powers, without the least defect. This is what the law of God requires, but what the saints cannot attain to in this life"

This quote by Charles Buck talks with the concept that although the regulation of God requires excellence, it is something that can not be attained in this life. It recommends that there is an excellence of levels, implying that a person can aim to do their best to meet the commands of God, but they will never be able to do so perfectly. This is because, as people, we are incomplete and also will certainly always make blunders. The quote suggests that although we should strive to do our best to comply with the legislation of God, we need to also approve that excellence is not feasible in this life. It is a reminder that although we ought to strive for quality, we need to additionally be kind to ourselves as well as accept that perfection is not achievable.
