During Jesus' desolation on the Cross his mind continued to believe but his human heart was tormented by his Father's perceived absence. At times the human heart can be overwhelmed with pain. In us, the great temptation in time of trial is doubt. It is very human to ask, If you love me so much, how can this be happening to me? Innumerable people including many saints have asked this question through history.
What we feel are the effects of sin: alienation from God and others. The sin is not necessarily our own, any more than it was for Jesus. He had no sin; yet he felt its effects. His passion was at the very center of what he had been sent to reconcile and heal: the human heart, desolate because of its sins, unable for the moment to feel the care of a loving God. He calls us to become sharers in his confidence in the Father and redemptive offering of himself to overcome sin and its effects.
I abandon myself to you, Lord. When I have neither the energy nor the will to do anything else I know that you understand. Accept my offering and overcome my doubts by the power of your Spirit.
