"When she had received mercy from God she owned it, with thankfulness to his praise. Praise is our rent, our tribute. We are unjust if we do not pay it. The mercy she had received was an answer to prayer, and therefore she thought herself especially obliged to give thanks for it. What we win by prayer we may wear with comfort, and must wear with praise. Her thanksgiving is here called a prayer: Hannah prayed; for thanksgiving is an essential part of prayer.
Observe, what great things she says of God. She takes little notice of the particular mercy she was now rejoicing in, does not commend Samuel for the prettiest child, the most toward and sensible for his age that she ever saw, as fond parents are too apt to do. No, she overlooks the gift, and praises the giver; whereas most forget the giver and fasten only on the gift. Every stream should lead us to the fountain; and the favors we receive from God should raise our admiration of the infinite perfections there are in God. There may be other Samuels, but no other Jehovah. There is none beside thee."
1 Samuel 2
"Thanksgiving is a proper answer to dark and disquieting thoughts, and may be an effectual means to silence them. Songs of praise are sovereign cordials to drooping souls, and will help to cure melancholy. When we have no other answer ready to the suggestions of grief and fear, we may have recourse to this, I thank thee, O Father; let us bless God that it is not worse with us than it is. "
