I recall an old quote that says:
“Don’t get overly elated when things go well and don’t get overly depressed when they go poorly.”
I think this is pretty sound advice.
We are tempted to swing to extremes.
And at those extremes we are tempted even more–by pride at one end and despair on the other.
Yet good days, bad days come and go.
And God makes one as well as the other (Ecc. 7:14).
So staying even-keeled makes sense.
But I would add a twist to the quote above:
Whether you are happy or hopeless, the Lord calls you to abide in Him.
And this, I believe, is the surest way to stay fruitful–no matter what your circumstances.
“He who abides in Me and I in him, he bears much fruit (Jn. 15:5).
