Pleasant Changes by Jane Browne Seasons poem

Summer's sun is warm and bright,
Winter's snow is cold and white,
Autumn brings the sheaves of grain,
Spring will scatter flowers again;
Pleasant changes
God arranges
All throughout the year!

First there's darkness then there's light,
First we've day and then we've night,
First we're hot and then we're cold,
First we're young and then we're old;
Are we knowing
Where we're going,
What we're doing here?
