The notion that Christians should always be optimistic and congenial is heresy pure and simple. An ill-founded optimism may, under certain conditions, be extremely harmful. A Christian is not obliged to be either pessimistic or optimistic or glad or sad or positive or negative after a preconceived rule of philosophy. He should (and will if he is Spirit-taught) reflect the will of God in any given situation. His one concern is with God’s will. His one question in any set of circumstances is “What does God think of this?” To him nothing else matters. What the current popular attitude may be is of no importance to him. He will approve or disapprove altogether as the written Word and the indwelling Spirit indicate. Religious vogues, passing moods or popular notions will affect him not at all. His heart is fixed, trusting in the Lord.
This rather rigid attitude will, in a world like ours, quite naturally work against the one who holds it and earn him a reputation as a pessimist. People like the man who agrees with them, even if a day later they change their minds and require him to change his, too. This inconsistency they laugh off as an amiable weakness, and why be so pious about it anyway?
Well, the sons and daughters of eternity care very little about this maypole dance of popular favor. Like the water bird on the shore of the lake at the approach of winter, they feel within them a strong instinct to migrate. They expect before long to take off on a journey and they’re not coming back soon. So whether they leave behind them a reputation for pessimism or optimism is of little consequence to them. They are, however, eager to be remembered as children of God and followers of the Lamb. That’s all that matters to them.
