Proverbs 21:27

v. 27. The sacrifice of the wicked is abomination, no amount of mechanical, outward acting will take the place of worship in spirit and in truth; how much more when he bringeth it with a wicked mind, for transgression, while his heart is still filled with wickedness, the outward sacrifice being intended to cover up the lack of repentance. This verse applies to all outward, mere mechanical worship, to all the churchgoing of hypocrites.
