Faith—not only in His existence, but His “all-wise Providence”
Faith does not consist of merely believing in the existence of God, but also in His all-wise Providence which guides His creatures and arranges everything for the good; the times and the seasons are put in His power (Acts 1:7), and for each of us the limits of our life were determined before our existence, and without His will a bird does not fall nor does a hair of our head perish! (Matt 10:29; Luke 21:28).
St. Macarius of Optina
