In Isaiah 1:11,14 God says, “I have had enough of burnt offerings…your new moons and your appointed festivals my soul hates.”
What’s THAT all about?
Didn’t He spend most of Exodus and Leviticus telling Moses and the Israelites in minute detail about what festivals they should celebrate and how? What burnt offerings they should be making? What grain offerings? What peace offerings?
So why is a God who never changes telling them He now hates those things?
It is because although the people claimed to be close to God, they were really disobedient and just going through the motions. Religion had become routine instead of real. And God knew that.
Just like He knows today who is coming to church to really worship Him… and who is just coming. Who is singing hymns of praise… and who is just singing.
Jesus quoted Isaiah’s condemnation of Israel’s hypocrisy when He spoke to the Pharisees in Matthew 15:7-9, “You hypocrites! Well did Isaiah prophesy of you when he said: this people honors me with their lips, but their heart is far from me; in vain do they worship me, teaching as doctrines the precepts of men.”
The key is faith not works.
Being a descendent of Abraham. Living in the Promised Land. Having trusted God at one time. None of these were good enough. We need to have faith in God. A personal relationship. That is why we are set apart. Ask yourself; are you relying on your Christian heritage? The rituals of worship? Past experience? Or do you have faith that puts you in a right relationship with your Heavenly Father?
God expects our belief in Him to penetrate all areas of our conduct and to extend to all people and circumstances. Amos 9:13-15
