Why did Jesus have the fishermen bring in that gigantic haul of fish? To display his power so that Simon and the others would know what kind of person they were going to follow? To cause Simon to recognize his own sinfulness in comparison with Jesus’ obvious holiness? As an object lesson about being fishers and God providing the catch, whether of fish or people? To provide a whole lot of free fish to the people (when the fishermen “left everything” behind as they followed Jesus)?
Whatever the exact purpose, Simon no doubt never forgot the amazement he felt. He must have gotten over his acute discomfort at being in close proximity with a man of such holiness and power, But the conviction that this man was the one to follow, the one with the word of God and the grace of God as well as the power of God, only grew stronger as he followed him.
We don’t know what kind of afflictions the psalmist has in mind, as he cries out to God for relief. Whatever it is, it has been going on for a long time, some number of years, apparently. But he knows also that God has always been with His people, and always will be. He knows that God’s love is steadfast, and he looks forward to a time of joy and evidence of God’s blessing.
