One reason why are told to “rejoice in the Lord always” is because all other things we might rejoice in will change. Circumstances change. People change. Interests change. When we look for our ultimate joy in something that isn’t steady and reliable, neither will our joy be. Circumstances can become unfavorable, people can become unpleasant and interests can become unfulfilling. But God doesn’t change! He never goes from good to bad. So, let us enjoy the gifts of God as a means of deeper joy in Him, remembering… We can have unending joy when we look for it in our unchanging God.
