“That same day Nadab and Abihu, Aaron’s sons, took their censers, put hot coals and incense in them, and offered “strange” fire to God – something God had not commanded. Fire blazed out from God and consumed them – they died in Gods presence.” – Leviticus 10:1-2 MSG
The bible says Aaron’s sons offered up strange fire to God in the context of a holy and sacred offering. They tried to mix holy with unholy and God consumed them; they died the same way they tried to cheat God. The moment you try to bring in an unholy thing into the holy things of God, you automatically negate the sacredness of a holy act. For example, the bible speaks on meditation; to meditate on the word of God but if you begin to practice yoga as a means of meditation, you are bringing “strange fire” into a sacred act. You cannot do yoga and expect it to be a good offering to the Lord because it is a spiritual practice that has its origin in offering incense to other gods.
In the same way, you cannot incorporate practices from other religions into your relationship with the Lord. It is strange fire that is an abomination to the Lord. While God is all loving, it’s important to be aware of your practices and habits. If it is not biblical or biblically supported, you should always bring it to the foot of the cross.
