Fr. Alexander Schmemann describes this as the sorrow that pervades the Lenten services that lead up to Pascha. He calls it “bright sadness.” Is not Lent itself a joyous gift from God? The Church Fathers refer to it not as a season of misery but of joy, a “springtime of the soul.”
It is a time to weed out the passions that trip us up on life. It is a time to focus on Christ and to find in Him our greatest joy. It is a time to ask God to heal us of all those things we hate about ourselves, all those things that mess up our lives and destroy us. Let us rejoice every time we discover a new imperfection because through repentance and godly sorrow that imperfection (sin) can lead to forgiveness, joy and newness of life. Bishop Kallistos Ware observes that the purpose of repentance “is to see, not what I have failed to be, but what by the grace of God, I can yet become.”
Lent was not given to us by the Church to make our lives miserable. It is a God-given opportunity to remove from our lives all those passions that enslave us to set us free to experience “the glorious liberty of the children of God.” It is this “joy-creating sorrow” or “bright sadness” that leads to repentance which, in turn, leads to salvation and explodes with joy at Pascha.
