You have heard it said that oil and water don’t mix. You can understand this concept better when you take a look at a bottle of salad dressing. You hold it up and you can see where things have settled and the oil and water have separated. In order to bring that oil and water back together, the bottle must be shaken. You set the bottle back down for a bit and in no time the oil and water separate because in a bottle of salad dressing the togetherness of the ingredients won’t last forever. They go back to their own department. They go back to separate rooms. They go back to separate seating places. They go back to separate communities. They go back because it is intrinsic to their nature that they will not mix.
Mayonnaise, on the other hand, does not have to be shaken even though it is also comprised mostly of oil and water. This happens because mayonnaise contains an emulsifier. An emulsifier is that which brings things together that which otherwise could never come together. The emulsifier in mayonnaise is an egg and the egg infiltrates both substances so they are able to come together and be a solid substance. The emulsifier that brings people together from different backgrounds and places into the church is the blood of Christ. Out of Jesus’ great love for us He went to the cross and now His sinless blood runs through His people by faith and acts as an emulsifier that makes us one “in Christ Jesus.”
