Sometimes we pray unceasingly for a favor we need. Then we also learn that we only need to ask, confidently believing that God will answer us, and relax. Should we strike a balance between these two approaches? I think of St. Monica petitioning persistently for the conversion of her son Augustine, the prayer of total abandonment to God of St. Therese, and the Lord's own earnest request during his agony in the garden. So I believe that how we ask depends upon what we ask for and our own spiritual state. Let the Holy Spirit be our sole guide. What's essential is that the petition come from the heart with the greatest possible faith.
