“As we have seen, there is a difference between what God is actually asking of us, and what we imagine He is asking. We won’t have the grace to do what God is not asking of us. But for what He is asking, He has promised His grace: God grants what He commands. When God inspires us to do something (if it really is God who is the source of the inspiration), at the same time He supplies the ability to do it, even if it is beyond our ability and scares us at the start. Every motion that comes from God brings both the light to understand what God intends, and the strength to accomplish it: light that illuminates the mind, and strength that gives power to the will.”
Fr. Jacques Phillipe
It is not unusual for those of us who are zealous for God, to want to do great and grand things for Him. We love God so, and want everyone else to love Him with their whole being.
