To me this leave seems a bit unusual. Most of the time a leaf is either green or gold, not half and half. Looks to me that someone picked this off the tree to make a point. And a good point it is; things change and change can be good. Once again this passage from the book of Ecclesiastes comes to mind.
Ecclesiastes 3:1-8 (WEB)
1) For everything there is a season, and a time for every purpose under heaven:
2) a time to be born, and a time to die; a time to plant, and a time to pluck up that which is planted;
3) a time to kill, and a time to heal; a time to break down, and a time to build up;
4) a time to weep, and a time to laugh; a time to mourn, and a time to dance;
5) a time to cast away stones, and a time to gather stones together; a time to embrace, and a time to refrain from embracing;
6) a time to seek, and a time to lose; a time to keep, and a time to cast away;
7) a time to tear, and a time to sew; a time to keep silence, and a time to speak;
8) a time to love, and a time to hate; a time for war, and a time for peace.
Things change, the fact is inescapable and in fact necessary. Yesterday I had my 62nd birthday. More than just a date, it marked my ability to collect Social Security (you know, the fund for OLD PEOPLE), but it wasn't until my birthday party, when the brought out the cake decorated with "old timer" that it hit me. I guess I am officially "OLD" now. But that's not so bad, because I feel like the leaf in the picture because I know that there is still some green in me yet. And when all of it is gone, my color will match the golden streets in heaven. Nice match, nice change.
