1 Samuel 15:22

And Samuel said, Hath the LORD as great delight in burnt offerings and sacrifices, as in obeying the voice of the LORD? Behold, to obey is better than sacrifice, and to hearken than the fat of rams.

Hath the Lord as great delight in burnt offerings ... Samuel must not be regarded as in any way disparaging the ordinances of the Mosaic law. The sacrifices had been appointed by divine authority, and therefore were to be duly performed. But they were merely expressive of the faith and piety cherished by the worshippers; and whenever the outward observance was considered of greater importance than the inward sentiment or the spiritual feeling, there was a perversion of religion which was displeasing to God. Obedience is the true test of a religious profession.
