C.H. Spurgeon:

“And Mary said, My soul does magnify the Lord, and my spirit has rejoiced in God my Savior.”  – Luke 1:46, 47.

Observe, this morning, the sacred joy of Mary that you may imitate it. This is a season when all men expect us to be joyous. We compliment each other with the desire that we may have a “Merry Christmas.” Some Christians who are a little squeamish do not like the word “merry.” It is a right good old Saxon word, having the joy of childhood and the mirth of manhood in it. It brings before one’s mind the old song of the midnight peal of bells, the holly and the blazing log. 

I love it for its place in that most tender of all parables, where it is written, that, when the long-lost prodigal returned to his father safe and sound, “They began to be merry.” This is the season when we are expected to be happy. And my heart’s desire is that in the highest and best sense, you who are Believers may be “merry.” 

Mary’s heart was merry within her—but here was the mark of her joy—it was all holy merriment, it was every drop of it sacred mirth. It was not such merriment as worldlings will revel in today and tomorrow, but such merriment as the angels have around the Throne of God, where they sing, “Glory to God in the highest,” while we sing, “On earth peace, good will towards men.” Such merry hearts have a continual feast.

I want you, you children of the bride-chamber, to possess today and tomorrow, yes, all your days, the high and consecrated bliss of Mary that you may not only read her words but use them for yourselves, ever experiencing their meaning—“My soul does magnify the Lord and my spirit has rejoiced in God my Savior.” Observe, first, that she sings. Secondly, she sings sweetly. Thirdly, shall she sing alone?”
