Coexist. What do you think of when you hear this term? I hear tolerance and acceptance. The term is widely used to promote embracing people with differing ideologies equally. Obviously the Bible does teach loving all people, including our enemies; but the coexist movement can very easily be misleading.
Some people I’ve spoken with about this take “coexist” as meaning: you can have your truth, I can have mine, and they are all valid. It seems to me that this philosophy is just a well-intentioned attempt at teaching relativism.
I’m afraid Christians may not want to hear this, or may not even realize this but Christianity does not allow relativism. Jesus himself declared: “I am the way and the truth and the life. No one comes to the Father except through me.” (John 14:6). I think that puts it pretty bluntly. If all that matters in this life is our eternal souls, and the only way to preserve that soul for eternity is to follow Christ, then this idea of relative truth is an extremely harmful philosophy!
Being tolerant of other religions does not mean we have to take it as far as authenticating their belief system as a valid source of truth. Christians should be standing on the authority of the word of God as our only source of absolute truth.
Of course we need to be respectful of all faith traditions, and not actively belittle or mock others, but when asked about our opinions we need to have a solid answer to give. We need to grow up in the faith following the lead in Ephesians 4:14 (NIV):
“Then we will no longer be infants, tossed back and forth by the waves, and blown here and there by every wind of teaching and by the cunning and craftiness of men in their deceitful scheming.”
