Very significant things may occur during our time of moulding. Job is a good example of this. He persevered during his tribulations and got a deeper understanding of who God is. In Job 2:9 he was even tempted to curse God and die, but he refrained. He questioned his friends and God, expressing his frustration, eg in Job21:1ff. God finally answered from chapter 38-41. Then the great restoration happens in chapter 42. May the Lord help us to preservere.
