I am rather fond of what the Royal Horticultural Society says of viburnum:

Viburnums are versatile, easy-to-grow shrubs that thrive in a wide range of situations. There are many to choose from, large or small, evergreen or deciduous, with winter, spring or summer flowers.

Versatility is certainly the right choice of word. Why cannot we Christians be more like this? Although we are a varied people ('large or small, evergreen or deciduous'), our spiritual growth is too easily stunted and reversed by a change in our conditions. To we of little faith does the Lord direct His discourse in Matthew 6. He urges us to consider the flowers of the field, that we might learn therefrom. May we be easy to grow and inclined to thrive, whatever the season.
