"Mr. Somebody" (a really popular guy) said, "The most constant thing in life is change."
Of course, there are exceptions to everything. God is the one thing that doesn't change. Oh, his ways of doing things change sometimes. He even changes his mind when circumstances call for it. However, God doesn't change in his nature. He is perfectly and consistently good. His ways, though they may change, are always righteous. "Your righteousness reaches to the skies, O God, you who have done great things." (Psalm 71:19) Everything else - everything - will be different tomorrow. Whether it's your age, body size, number of teeth, amount or color of hair, amount of money - things will change.
Actually, we, and the universe we live in, are made for change. Living things come into existence through the reproduction process, grow to maturity, and then die. Non-living matter changes as well, through the effects of the elements...wind, rain, sun, etc. Think about it. Without change, this would be a pretty boring world, wouldn't it? At least, compared to the complexity of what we know now. Scripture, then, as one writer said, views change as "imbedded in the very nature of the created universe." (NIV Encyclopedia of Bible Words) And, as we look at the universe, it seems pretty obvious that God loves change. It's hard to observe the changing of the seasons (at least, in our latitude) without being impressed by the beauty inherent in those changes.
Change is important in other areas as well. Few among us would claim we should never change our minds on any subject. "Opinions are like noses; everybody has one." But refusing to change our views when the evidence warrants it is an indication of foolish stubbornness.
Moral changes are certainly needed from time to time by most of us. We can develop habits that are physically, emotionally and spiritually unhealthy. These need to be changed if we want to live a better life.
The most important change anyone can make is one of spiritual allegiance. "Who rules my life?" is a question we all need to honestly ask ourselves from time to time. If the answer isn't "God," change is needed, and needed quickly. Here is a promise that will help us: "Commit your way to the LORD; trust in him and he will do this: He will make your righteousness shine like the dawn, the justice of your cause like the noonday sun." (Ps. 37:5-6)
Ultimately, as the apostle Paul wrote, "we will all be changed--in a flash, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, the dead will be raised imperishable, and we will be changed" (1 Co 15:51-52). On that day, the most dramatic change imaginable will take place, when the dead are raised. What a day of glory it will be for those who are ready for that change!
