Quite simple No. God accepts worship that is of him through Jesus, so all religions that do not worship God through Jesus are not worshipping God.
Why did God send the Jews into exile in the Old Testament? answer because they stopped worshipping God and worshipped other false gods.
So God does not accept worship from or through other religions.
This brings to mind the Apostle Paulās words at the Areopagus in Athens:
āFor as I passed along and observed the objects of your worship, I found also an altar with this inscription: āTo the unknown god.ā What therefore you worship as unknown, this I proclaim to you.ā
I believe God accepts the worship of all those who are sincerely seeking him, and if they continue to seek him sincerely, even if they donāt know much about him or have some things wrong about him (we probably all do, if weāre honest), he will reveal more of who he is to them.
Thatās not necessarily the same as accepting worship of every religion, though. I think purposefully worshipping other gods or deities is worshipping idols, which the Bible condemns strongly many times.
I think thereās an important difference between sincerely seeking God and the idea that all beliefs are automatically the same.
What stands out to me in the Bible is that God seems very responsive to people who genuinely seek Him, even when their understanding is incomplete. At the same time, Christianity also makes very specific claims about Jesus and who He is.
So I personally see it less as āall religions are identicalā and more as recognizing that people may be at different places in their understanding and journey.
