"God seeth different abilities and frailties of men, which may move His goodness to be merciful to their different improvements in virtue"

This quote by William Law talks to the idea that God knows the different capacities as well as weak points of each specific person. He identifies that everyone is unique as well as has various degrees of merit. This understanding of humanity leads God to be merciful and also forgiving of those who are not as virtuous as others. God's grace is not based upon an individual's degree of merit, however instead on His very own goodness and understanding of the person. He wants to forgive and show grace to those that are not as virtuous as others, since He knows that everyone has different abilities and also weak points. This quote is a pointer that God is a caring and forgiving God, which He wants to reveal grace to all, despite their level of merit.
