On religion and a relationship with God

One last thought from reading through Isaiah 1:

11 “The multitude of your sacrifices—
what are they to me?” says the LORD.
“I have more than enough of burnt offerings,
of rams and the fat of fattened animals;
I have no pleasure
in the blood of bulls and lambs and goats.
12 When you come to appear before me,
who has asked this of you,
this trampling of my courts?
13 Stop bringing meaningless offerings!
Your incense is detestable to me.
New Moons, Sabbaths and convocations—
I cannot bear your worthless assemblies.
14 Your New Moon feasts and your appointed festivals
I hate with all my being.
They have become a burden to me;
I am weary of bearing them.
15 When you spread out your hands in prayer,
I hide my eyes from you;
even when you offer many prayers,
I am not listening.

- Isaiah 1:11-15

God SO clearly hates religion and seeks a relationship with Him, He, Himself. Look at all the rituals described in the first few verses - sacrifices, offerings - acts that would've been the markers of 'holy' people back in the day. They're doing okay, right? NO. As God carries on talking, it becomes clear that the Israelites have lost the plot and are indulging in acts of worship of other gods (New Moon feasts etc). And God's not pleased. If it's going to be half-hearted, He don't want no part in it at all.
