Psalms 50:8

To obey is better than sacrifice, and to love God and our neighbour better than all burnt-offerings. We are here warned not to rest in these performances. And let us beware of resting in any form. God demands the heart, and how can human inventions please him, when repentance, faith, and holiness are neglected? In the day of distress we must apply to the Lord by fervent prayer. Our troubles, though we see them coming from God's hand, must drive us to him, not drive us from him. We must acknowledge him in all our ways, depend upon his wisdom, power, and goodness, and refer ourselves wholly to him, and so give him glory. Thus must we keep up communion with God; meeting him with prayers under trials, and with praises in deliverances. A believing supplicant shall not only be graciously answered as to his petition, and so have cause for praising God, but shall also have grace to praise him.

I will not reprove thee for thy sacrifices or thy burnt offerings, to have been ever before me. Though they had not failed in maintaining his outward worship, or even if they had, he was not about to call them to account for this: a more weighty matter was now under consideration. They thought the daily sacrifices and the abounding burnt offerings to be everything: he counted them nothing if the inner sacrifice of heart devotion had been neglected. What was greatest with them was least with God. It is even so today. Sacraments (so called) and sacred rites are them main concern with unconverted but religious men, but with the Most High the spiritual worship which they forget is the sole matter. Let the external be maintained by all means, according to the divine command, but if the secret and spiritual be not in them, they are a vain oblation, a dead ritual, and even an abomination before the Lord.
