Life is full of trials: we make mistakes, we get sick, we lose people we care about. Sometimes my tendency is to view life like a puzzle, something to be solved. When I lose a piece, I'm sunk. Once a piece is missing, there is essentially no way to complete the picture.
However, a more correct comparison would be to say that life is like a painting. We may make a mistake here or there but a true artist can easily turn those blemishes into an overall beautiful picture.
Elder Bednar relates the following in one of his conference addresses:
"In my office is a beautiful painting of a wheat field. The painting is a vast collection of individual brushstrokes—none of which in isolation is very interesting or impressive. In fact, if you stand close to the canvas, all you can see is a mass of seemingly unrelated and unattractive streaks of yellow and gold and brown paint. However, as you gradually move away from the canvas, all of the individual brushstrokes combine together and produce a magnificent landscape of a wheat field. Many ordinary, individual brushstrokes work together to create a captivating and beautiful painting."
Each day we paint a little bit more. And hopefully we don't get discouraged if things maybe don't turn out how we planned or if we feel like we messed up. With God's help, we can improve our lives/paintings each day.
