Didn't the Israelites make the golden calf to worship the God who brought them out of the land of Egypt? That still made God mad. Yet to the Israelites they were worshipping Him in their own idolatrous ways.
So wouldn't that also apply to Easter? People say they are honoring Jesus, but they are using idolatrous ways to worship Him when God specifically said not to?
Jeremiah 17:9 KJV
"The heart is deceitful above all things, and desperately wicked: who can know it?"
We think in our hearts we're doing a good thing, but who truly knows their own heart? Only God knows it. Not even ourselves know our own heart.
