O taste and see that the LORD is good: blessed is the man that trusteth in Him. – Psalm 34:8

We can recollect the sayings of great men; we treasure up the verses of renowned poets; ought we not to be profound in our knowledge of the words of God? The Scriptures should be the classics of a Christian, and as our orators quote Homer, or Virgil, or Horace, when they would clinch a point, so we should be able to quote the promises of God when we would solve a difficulty or overthrow a doubt. “He hath said,” is the foundation of all riches and the fountain of all comfort, let it dwell in you richly as “a well of water, springing up unto everlasting life.” And, oh, my brethren, how diligently should we test the Scriptures! Besides searching them by reading, and treasuring them by memory, we should test them by experience, and so often as a promise is proven to be true we should make a mark against it, and note that we also can say, as did one of old, “This is my comfort in my affliction: for Thy word hath quickened me.” “Wait on the Lord,” said Isaiah, and then he added “Wait, I say, on the Lord,” as if his own experience led him to echo the voice of God to his hearers. Test the promise, take God’s banknote to the counter, and mark if it be cashed. Grasp the lever, which He ordains to lift your trials, and try if it possesses real power. Cast this divine tree into the bitter waters of your Marah, and learn how it will sweeten them. Take this salt, and throw it into the turbid waters, and witness if they be not made sweet, as were the waters of old by the prophet Elisha. Taste and see that the Lord is good, for there is no want to them that fear Him.

“He hath said;” let us do the same, for, though the words of ministers may be sweet, the words of God are sweeter; and though original thoughts may have the novelty of freshness, yet the ancient words of God have the ring, and the weight, and the value of old and precious coins, and they shall not be found wanting in the day when we shall use them. ~ C.H. Spurgeon
