Charles H. Spurgeon on Psalms 97:10

Ye that love the Lord, hate evil. For He hates it, his fire consumes it, his lightnings blast it, his presence shakes it out of its place, and his glory confounds all the lovers of it. We cannot love God without hating that which he hates. We are not only to avoid evil, and to refuse to countenance it, but we must be in arms against it, and bear towards it a hearty indignation. He preserveth the souls of his saints. Therefore they need not be afraid of proclaiming war with the party which favours sin. The saints are the safe ones: they have been saved and shall be saved. God keeps those who keep his law. Those who love the Lord shall see his love manifested to them in their preservation from their enemies, and as they keep far from evil so shall evil be kept far from them. He delivereth them out of the hand of the wicked. It is not consistent with the glory of his name to give over to the power of his foes those whom his grace has made his friends. He may leave the bodies of his persecuted saints in the hand of the wicked, but not their souls, these are very dear to him, and he preserves them safe in his bosom. This foretells for the church a season of battling with the powers of darkness, but the Lord will preserve it and bring it forth to the light.
