Charles H. Spurgeon on Psalms 119:145

I cried with my whole heart. As a man cries most loudly when he cries with all his mouth opened; so a man prays most effectually when he prays with his whole heart. Neither doth this speech declare only the fervency of his affection; but it imports also that it was a great thing which he sought from God. And thou, when thou prayest, pray for great things; for things enduring, not for things perishing: pray not for silver, it is but rust; nor for gold, it is but metal; nor for possessions, they are but earth. Such prayer ascends not to God. He is a great God, and esteems himself dishonoured when great things with great affection are not sought from him. William Cowper.
