When a trial comes we cast about looking for an anchor. A great part of the pain of a trial comes from fearing what will happen; our emotions throw us about; our limited knowledge parades as wisdom. We cannot keep ourselves still or safe and so we need a knowledge and faith which will hold us safe.
Polhill explains that such faith may be had, but only a faith cast upon God:
Faith hath a respect to God; it makes its approaches to him, nay, it fixes the soul in him as in its centre. Hence it is that the “righteous fears no evil tidings, because his heart is fixed, trusting in the Lord,” (Psalm 112:7). The world rolls about, but he by faith stands fast in the unmoveable God. Hence it is that the church becomes unmoveable too. “God is in the midst of her, she shall not be moved,” (Psalm 46:5).
A Preparation for Suffering
