When others behave badly to us, it should only stir us up the more heartily to give thanks unto the Lord, because He is good; and when we ourselves are conscious that we are far from being good, we should only the more reverently bless Him that He is good. We must never tolerate an instant’s unbelief as to the goodness of the Lord; whatever else may be questioned, this is absolutely certain, that Jehovah is good; His dispensations may vary, but His nature is always the same.
– C.H. Spurgeon
