People are always trying to improve things from cars to computers, and even phones. How would you feel if you went out to buy the newest iPhone and they hand you the iPhone 3? You know the iPhone 12 has better technology than the iPhone 3, so why would you want the old, obsolete version. This is what the Christians being written to in the book of Hebrews are doing. They have the new, better, easier law, but they are trying to follow the old, obsolete, harder law. Why would anyone want to do that? If there is an easier way to do something effectively, that seems like the smarter thing to do.
The iPhone 3 had its purpose. It led to the iPhone 12. There are similarities to both because they are both Apple products, however, the iPhone 3 is no longer useful because we have the iPhone12. The iPhone 3 led to the iPhone 12, and the iPhone 12 will lead to the iPhone 17. The Christians being written to in Hebrews, however, have been given the best and final version of salvation as mentioned in Jude vs. 3 “...I found it necessary to write to you exhorting you to contend earnestly for the faith which was once for all delivered to the saints.” These Christians are trying to go back to an earlier “draft” of the plan.
It would be like if you decided to go on a diet. You got some friends to join you and help you. You have the diet plan, and it is separated by phases. You and your friends get to the final phase and some of your friends want to go back to phase 2. You and your friends worked so hard to get here and they are going backward. They are throwing their progress out the window. The point of the diet was to get to the end, not get to the end, and go back to the middle. The Christians being written to in Hebrews are doing something similar. They are in the final stage of the plan and they are going back to the middle.
People today can do something similar. They can become Christians and then go back to a life of sin. We should never do this. We, as faithful Christians, must always help these people to remember that Jesus is better.
