To Know or Experience God
It must be your constant goal to know God. Study of Scripture, the teachings of the Church, and the lives of the saints all help in this endeavor. But knowing God is not the ultimate goal of life. Knowledge comes from faith and faith is a gift from God. But being fully united to God in charity is of far greater importance. They are not opposed, but they are not the same. In fact, at times the Lord will darken one's mind and not even allow it to understand Him so that He can, instead, transform the will so that this holy soul will choose Him and live a life of charity even in the darkness of faith. This is a deep mystery (See Diary #1697).
Devotion to the souls in Purgatory contains in itself all the works of mercy, which supernaturalized by a spirit of faith, should merit us Heaven. de Sales
