What does the Bible say about worshiping alongside other religions?

In Exodus 8 and 9, we see a clear distinction made between the worship of the true God and that of false deities. Pharaoh's proposal to worship alongside his gods was rejected by Moses, who asserted that it is not right to do so, as true worship cannot coexist with falsehood. This illustrates the biblical principle that light cannot have fellowship with darkness (2 Corinthians 6:14). True believers are called to come out from among false religions and maintain the integrity of the gospel of grace without compromise.
