“If we rely on anything else besides faith to maintain the practice of the presence of God, we will certainly fail, whether this is our feelings, or experiences, or sincerity, or good intentions, or reasonings, or plans. The reason these things will fail while faith will not fail is that all these things depend on us, while faith depends on God. It is a gift of God.”
