Hebrews 13:16

Verse 16. But to do good and to communicate] These are continual sacrifices which God requires, and which will spring from a sense of God's love in Christ Jesus. Praise to God for his unspeakable gift, and acts of kindness to men for God's sake. No reliance, even on the infinitely meritorious sacrifice of Christ, can be acceptable in the sight of God if a man have not love and charity towards his neighbour. Praise, prayer, and thanksgiving to God, with works of charity and mercy to man, are the sacrifices which every genuine follower of Christ must offer: and they are the proofs that a man belongs to Christ; and he who does not bear these fruits gives full evidence, whatever his creed may be, that he is no Christian.
