Charles H. Spurgeon on Psalms 147:11

Them that fear him, those that hope in his mercy. A sincere Christian is known by both these; a fear of God, or a constant obedience to his commands, and an affiance, trust, and dependence upon his mercies. Oh, how sweetly are both these coupled, a uniform sincere obedience to him, and an unshaken constant reliance on his mercy and goodness! The whole perfection of the Christian life is comprised in these two —believing God and fearing him, trusting in his mercy and fearing his name; the one maketh us careful in avoiding sin, the other diligent to follow after righteousness; the one is a bridle from sin and temptations, the other a spur to our duties. Fear is our curb, and hope our motive and encouragement; the one respects our duty, and the other our comfort; the one allayeth the other. God is so to be feared, as also to be trusted; so to be trusted, as also to be feared; and as we must not suffer our fear to degenerate into legal bondage, but hope in his mercy, so our trust must not degenerate into carnal sloth and wantonness, but so hope in his word as to fear his name. Well, then, such as both believe in God and fear to offend him are the only men who are acceptable to God and his people. God will take pleasure in them, and they take pleasure in one another. —Thomas Manton.
