There are certain evidences of the validity of a Christian’s faith but none more obvious than a heart, once was cold and self-serving, now beats warm with tenderness.
I will give you a new heart and put a new spirit in you; I will remove from you your heart of stone and give you a heart of flesh (Ezekiel 36:26, NIV).
Says Spurgeon, “It is a great covenant promise that the heart will be renewed, and the particular form of its renewal is this— that it will be made living, warm, sensitive, and tender.
It is naturally a heart of stone; it is to become, by a work of divine grace, a heart of flesh.
Therefore, much of the result of regeneration and conversion will be found to lie in the production of a tender spirit. Tenderness—the opposite of what is stout, obstinate, cold, and hard—is one of the most gracious signs in a man’s character.
And where God has given fleshiness, or living sensitiveness instead of stoniness or dead insensibility of heart, there we may conclude that there is a real work of grace and that God has created vital godliness within.”
