The first time I heard this song, at a community Christmas concert a few years ago, it took my breath away. What a huge burden of responsibility Mary must have felt, to carry the Christ child. Surely she must have needed the comfort and reassurance of the Spirit constantly. I'm sure she had guardian angles around her at all times.
I believe we all have times when the burdens we have to bear seem too much. What I love about this song is the message of reaching out to God to help us do what we have to do, and even just to exist from day to day. "Help me be strong. Help me be. Help me." We have heavenly help available to us too, if only we will ask.
