The first and greatest commandment is this: “You shall love the Lord your God with all your heart, with all your soul, with all your strength, and with all your mind.” Medieval monk and church leader St. Bernard of Clairvaux explores four stages of love by which the follower of Christ moves from selfishness deeper and deeper into a life of all-consuming love for Almighty God. His deeply insightful words, penned centuries ago, ring just as inspiring and true today as they did the day they were written.
