Hebrews 13:15-16

Even though God does not require periodic animal and vegetable sacrifices from us, we should offer other sacrifices to Him. These sacrifices include praise (cf. Hosea 14:2), good works, and (even, especially) sharing what we have with others (as well as giving Him ourselves, Romans 12:1). We should offer these sacrifices of the New Covenant continually.

"In systems like Judaism sacrifices were offered at set times, but for Christians praise goes up all the time." [Note: Morris, p. 151. Cf. Moffatt, pp. 236-37.]
