While your reference talks about prayer which is distinct from worship, I think that the instructions around prayer and worship are related. However, I dont think the message is to be reserved, but instead be honest. I understand this verse to mean don't be fake, God knows your heart. Be real. Here are a few examples that reinforce why I think this. When talking to the Samaritan woman at the well Jesus talks about worship being true and of the spirit. John 4:23-24 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. [24] God is spirit, and his worshipers must worship in the Spirit and in truth. A reminder to forgive and seek forgiveness from those you have wronged (as reinforced in Matthew 6:14-15, Leviticus 19:18, Proverbs 17:9 ) before asking for forgiveness and before worshipping God: Matthew 5:23-24 NIV [23] “Therefore, if you are offering your gift at the altar and there remember that your brother or sister has something against you, [24] leave your gift there in front of the altar. First go and be reconciled to them; then come and offer your gift. Showing that fake worship means little: Matthew 15 8:9 (NIV) quoting Isaiah 29:13 [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.’ ”
