The theme of it? The lesson? Be light, walk in a lighter way on this journey. Carry less. Let go. It will allow the Lord to take me to places, farther place, more easily.
The image of the pencil grip came to my mind.
If we push hard on the pencil while writing, it will tire us faster, it takes much more effort to write, and we will have more difficulty erasing our mistakes.
If we have a lighter grip on that pencil while writing, we will write more smoothly, faster, with more ease. The experience will be more pleasurable. And thus we will end up writing more.
Walk in the same way through life. With lighter feet. Carrying almost nothing. And you will walk to further places. More smoothly. And mistakes, wrong turns, will be easily corrected.
