Charles H. Spurgeon on Psalms 74:12

For God is my King of old. How consoling is this avowal! Israel in holy loyalty acknowledges her King, and claims to have been his possession from of old, and thence she derives a plea for defence and deliverance. If the Lord be indeed the sole monarch of our bosoms, he will in his love put forth his strength on our behalf; if from eternity he has claimed us as his own, he will preserve us from the insulting foe. Working salvation in the midst of the earth. From the most remote period of Israel's history the Lord had worked out for her many salvations; especially at the Red Sea, the very heart of the world was astonished by his wonders of deliverance. Now, every believer may plead at this day the ancient deeds of the Lord, the work of Calvary, the overthrow of sin, death, and hell. He who wrought out our salvation of old will not, cannot desert us now. Each past miracle of grace assures us that he who has begun to deliver will continue to redeem us from all evil. His deeds of old were public and wrought in the teeth of his foes, they were no delusions or make believes; and, therefore, in all our perils we look for true and manifest assistance, and we shall surely receive it.
