Full quote in context:
“To see and evaluate things from God’s perspective calls for constant conversion in the first days and years of our vocation and, need I say, great humility. The cross shows us a different way of measuring success. Ours is to plant the seeds: God sees to the fruits of our labors. And if at times our efforts and works seem to fail and produce no fruit, we need to remember that we are followers of Jesus… and his life, humanly speaking, ended in failure, the failure of the cross”
