Matthew Henry on 2 Kings 7:1-2

Man's extremity is God's opportunity of making his own power to be glorious: his time to appear for his people is when their strength is gone. Unbelief is a sin by which men greatly dishonour and displease God, and deprive themselves of the favours he designed for them. Such will be the portion of those that believe not the promise of eternal life; they shall see it at a distance, but shall never taste of it. But no temporal deliverances and mercies will in the end profit sinners, unless they are led to repentance by the goodness of God.
