Philippians 4:11 (NKJV)
There is a saying about something being "set in stone" that refers to something that is settled, something that is not going to change. This is the opposite of the phrase, "Subject to change without notice", which refers to something that could possibly be altered and how that could even happen without prior warning. If given a choice, most people would prefer something "set in stone" to something that is "subject to change without notice", but the reality is that there are many things in life that can be subject to change and we have no control over those things, the only thing we can truly control is how we respond to change.
None of us, when we are born, received a guidebook for life that showed us everything that would take place, when, or how it would happen. But, if we had, it may have had something written on the cover like, "this is not set in stone" or "subject to change without notice". This is because life is full of things that are subject to change. It is not a question of whether there will be any changes in our life, but it is a matter of our learning to be able to deal with the inevitable changes we will all face as well as being at peace and having joy no matter what comes.
Some people like the security they have in their way of life, they think they know exactly how things should be, so they don't like it when things change, they become inflexible. When something new comes along that challenges their set ideas they resist a change, even if it is for the better. This does not mean, however, that every time something new comes along we change what we are doing, that is not being flexible, that is being gullible. As we go through life, and especially as we come to a New Year, we need to have a proper attitude about things by not only realizing that things will change but that sometimes a change is necessary.
