Charles H. Spurgeon on Psalms 50:23

Whoso offereth praise glorifieth me. Praise is the best sacrifice; true, hearty, gracious thanksgiving from a renewed mind. Not the lowing of bullocks bound to the altar, but the songs of redeemed men are the music which the ear of Jehovah delights in. Sacrifice your loving gratitude, and God is honoured thereby. And to him that ordereth his conversation aright will I shew the salvation of God. Holy living is a choice evidence of salvation. He who submits his whole way to divine guidance, and is careful to honour God in his life, brings an offering which the Lord accepts through his dear Son; and such a one shall be more and more instructed, and made experimentally to know the Lord's salvation. He needs salvation, for the best ordering of the life cannot save us, but that salvation he shall have. Not to ceremonies, not to unpurified lips, is the blessing promised, but to grateful hearts and holy lives. O Lord, give us to stand in the judgment with those who have worshipped thee aright and have seen thy salvation.
