Imagine you own a 1988 Honda Accord. Over the years, you have put over a quarter of a million miles on “old faithful.” As you can imagine, the interior is ripped and torn from those miles. The engine uses oil. The transmission slips going from first to second. The body is rusted and worn, both inside and out. Although she may not have been abused, visibly it is evident the car has been driven for nearly 25 years. But… you love that car. So, instead of buying a new one, you invest in your car and put everything new into it. You put a new engine, a new transmission, and all new interior. From bumper to bumper, hood to trunk, radiator to tail pipe, front light to tail light, you replace the old with new.
Is this the same car that you bought back in 1988? Well, yes and no. Yes, it is the same “car,” but it has been rebuilt or re-created. The car has been changed completely other than how it is identified.
It is with this same sense that the gospel not only transforms a believer but changes everything. The Bible says in 2 Corinthians 5:17 “therefore, if anyone is in Christ, he is a new creation.” Jesus described this to Nicodemus in John 3 when he said, “you must be born again.” Ephesians 2 says the believer is “created in Christ Jesus.” The gospel changes everything for the believer because the old is put off (sin) and new is put on (Christ.)
Just like an old car completely re-built totally effects everything within the car, so too the gospel effects everything within the life of a believer.
