Union in suffering
When suffering comes — illness, loss, betrayal, dryness in prayer — unite it consciously to the Heart pierced for love.
Why this practice
There is a place in the Sacred Heart devotion for what older spiritual writers called the victim soul — the soul that consciously offers its own suffering, joined to Christ's, for the salvation of others. This is not a vocation for everyone in the same form; but every Christian eventually meets suffering, and what one does with it can be the deepest act of the Sacred Heart devotion.
St. Margaret Mary herself lived this; so did St. Thérèse of Lisieux, St. Faustina, and countless others. The pierced Heart and the pierced soul become, in suffering, one heart.
How to begin
I rejoice in my sufferings for you, and in my flesh I complete what is lacking in Christ's afflictions for the sake of His body, that is, the Church.
— Colossians 1:24
A prayer for this practice
Sacred Heart of Jesus, pierced for me, take what little I can offer. Let my small suffering — joined to Thine — be salt and light for those who need it. Where I cannot understand, let me trust Thee.
Amen.
