“When living in an egotistical age, it is hard to convince people that what they give to God sincerely may not be acceptable to Him. Narcissism imagines that God must simply melt at the sight His child’s scribble-drawing, knowing how sincere the amateurish effort was. Scripture shatters this pleasantly self-satisfied view.
“We think of Aaron and Israel making a symbol of Yahweh out of gold, declaring ‘Tomorrow is a feast day unto Yahweh!’ (Exod. 32:5). God suggested to Moses that an appropriate response to this kind of worship would be to annihilate the entire nation.”
He includes 10 other Scriptural examples and ends with this line.
“The lesson from all this must be that God does not accept worship merely because it is offered in His direction.”
