If those to whom God in His grace has committed a testimony do not employ this testimony in behalf of others according to the grace that bestowed it, they will soon become unfaithful in their own walk before God. If they truly acknowledged God, they would feel bound to make known His name and to impart this blessing to others. If they do not own His glory and His grace, they will assuredly be unable to maintain their own walk before Him. God, who is full of grace, being our only strength, it cannot be otherwise.
J. N. Darby (Synopsis on Jonah)
