I'm so glad for this simple little verse. It reminds me of the great depth of love and self sacrifice that is possible between Christ's followers. It makes me think of the love that has filled our hearts for the brethren ever since His love has been shed abroad in our hearts. It is a beautiful thing.
At the same time though I know the very act of bearing other's burdens is rocky ground and we can very easily add to their burden instead of ease it.
