Matthew 15:7-9 (NIV)
7 You hypocrites! Isaiah was right when he prophesied about you: 8 “‘These people honor me with their lips, but their hearts are far from me. 9 They worship me in vain; their teachings are merely human rules.’
Psalm 150 (NIV) 1 Praise the Lord. Praise God in his sanctuary; praise him in his mighty heavens. 2 Praise him for his acts of power; praise him for his surpassing greatness. 3 Praise him with the sounding of the trumpet, praise him with the harp and lyre, 4 praise him with timbrel and dancing, praise him with the strings and pipe, 5 praise him with the clash of cymbals, praise him with resounding cymbals. 6 Let everything that has breath praise the Lord. Praise the Lord.
John 4:23 (NIV) 23 Yet a time is coming and has now come when the true worshipers will worship the Father in the Spirit and in truth, for they are the kind of worshipers the Father seeks.
