Psalms 107:43

Whoso is wise and will observe these things, he who will take note of these facts, profit by the example of others, even they shall understand the loving kindness of the Lord, they will keep His merciful dealings in mind always. It is a lesson which cannot be learned too well or repeated too often, a lesson which all true Christians hold before their eyes every day, lest they forget their debt to the Lord and become lax in His service.
