You can hardly go anywhere these days without hearing the Pharrell Williams song, “Happy.” A report by Carol Graham of the Brookings Institute may indicate that it will not resonate with people uniformly through the life cycle, at least as Brookings Institute report might indicate.
Apparently there is a worldwide trend for people to have a U-shaped pattern to their life-long degree of happiness. Middle age is tough, it seems. Well, middle age can be especially tough. I would not want to minimize, having had my own very low times, how difficult certain seasons and circumstances of life can be. But there is hope to sustain us through those times.
In Romans 15:13 Paul indicates that there is a happiness that does not depend on circumstances. There is joy, which is not to be taken necessarily as a jump-up-and-down kind of thing (though it certainly can be), but is based on the certain knowledge that there is the Lord who loves and values us, and has a purpose for us. We know of this, and put it into practice in various ways, through the welcoming of the Holy Spirit.
And, as the context Romans 15:13 makes clear, mutuality of acceptance and service is key to experiencing such enduring inner peace.
