I will never forget a simple but impactful greeting card which I've seen years ago. It was drawn in cartoon and it conveys an endearing and encouraging message that is applicable to all who are downcast.
It shows a dejected little lamb sitting helplessly by the lake, looking despondent and staring aimlessly into the water. In its misery, it has failed to notice that its reflection has that of Jesus sitting by its side! Lo and behold, the invisible Good Shepherd has in fact an arm around the little lamb, quietly supporting and comforting it!
That card speaks volume! And it is still speaking to me today.
