Charles H. Spurgeon on Psalms 145:19

He will fulfil the desire of them that fear him: that is, those who reverence his name and his law. Inasmuch as they have respect unto his will, he will have respect unto their will. They shall have their way for they have his way in their hearts. A holy heart only desires what a holy God can give, and so its desire is filled full out of the fullness of the Lord. He also will hear their cry, and will save them. Divinely practical shall his nearness be, for he will work their deliverance. He will listen to their piteous cry, and then will send salvation from every ill. This he will do himself personally; he will not trust them to angels or saints.
