Charles H. Spurgeon on Psalms 18:24-27

Even as the sun, which, unto eyes being sound and without disease, is very pleasant and wholesome, but unto the same eyes, when they are feeble, sore, and weak, is very troublesome and hurtful, yet the sun is ever all one and the selfsame that was before; so God, who hath ever shown himself benign and bountiful to those who are kind and tender-hearted towards his saints, and are merciful to those who show mercy. But unto the same men, when they fall into wickedness and grow to be full of beastly cruelty, the Lord showeth himself to be very wrathful and angry, and yet is one and the same immutable God from everlasting to everlasting. —Robert Cawdray.
