It is serious, however...

“…it is an occupational hazard of religious people to take life (and themselves) far too seriously. This is because life is serious business: heaven and hell are serious matters; sin and repentance and obedience are serious concerns. But, ‘Be not anxious’ is the way we are to deal with all of life’s seriousness. Frankly, most of the ‘momentous issues’ we face in our daily living are not in the least momentous. Most of the time whether a decision goes this way or that makes little difference; our lives will go on. To be sure, there are decisive moments and genuinely tragic events, but they are much fewer than we imagine … relax, enjoy the little ‘inconveniences’ of our days, and rest easy in the God who has the whole world in His hands.
