If one of them falls into a clay pot, everything in it will be unclean, and you must break the pot. Any food that could be eaten but has water on it from such a pot is unclean, and any liquid that could be drunk from it is unclean. – Leviticus 11:33-34
This passage is from a larger section on clean and unclean food. It addresses what to do if an unclean animal such as a lizard or a rat dies and falls into a pot used for cooking. Sin damages all that it touches. The people of God were not only to avoid those things the Lord had declared unclean but anything those things came in contact with.
We should never think we can sin in isolation or in ways that have no consequences beyond ourselves. Any time we sin the entire web of relationships we’re involved in is damaged. This may be directly as a result of the sin committed or indirectly as a result of our diminished capacity to relate to people as we should because of our sin.
Either way, we never sin in a vacuum. Sin contaminates all that it touches. Remember when tempted: what seems so attractive in the moment will lead to consequences you didn’t anticipate.
