There is No Teacher Like God

What Elihu is trying to tell Job is that during this time of his distress and affliction he needs to remember to magnify God's work as far as he has learned it by his own experience. This will have great relevance for us, as to how God sovereignly brings grace to His dearly beloved people, and how He providentially orders the trials that we go through, and what we should learn by them to make us more fit to meet Him face to face, as each of us someday shall. There is no teacher like God, and so it will be good if we can learn from His works of creation, just how great His work in our salvation and sanctification is, through our Lord Jesus Christ.
