Just as Jesus is the model for everything else in our spiritual lives he is also the model for great and unavoidable suffering. The agony in the Garden led to the passion and the cross. Jesus' expectation of resurrection was not an expectation for this life. Jesus resurrection was definitely an event in his hereafter. At the time of the agony he was asked to abandon himself entirely until he died. Jesus clearly showed that no one needs to want this pain. He didn't want the pain; he didn't want the passion. It is true that he looked forward to the fulfillment. Nevertheless, the path to that fulfillment, the Way of the Cross, caused him great distress.
When we are tempted to think that suffering and anxiety are interfering with our relationship with the Lord, making it impossible for us to pray, it is useful to remember Jesus' prayer in the Garden. This is a prayer which is simply union with Jesus in his agony.
I want to be one with you, Jesus, in everything you experienced for love of me. I want to rejoice with you and grieve with you. All that really matters to me is to be always united with you.
