Luke 2:41-52 - The Hymn of the Day is Within the Father’s House (Lutheran Service Book #410)It recounts the Gospel reading of the Boy Jesus in the temple, and then offers up a prayer in stanzas 5 and 6 that we, by grace, might grasp and hold to the mysteries of the Incarnation and the Holy Trinity till they are at last made fully known to us on that great day when our Lord returns in majesty and glory.
The Son hath found His home;
And to His temple suddenly
The Lord of Life hath come.
Gaze on the wondrous child,
And marvel at His gracious words
Of wisdom undefiled.
And know, as we are known,
Thee, Father, Son, and Holy Ghost,
Co-equal Three in One.
for the Second Sunday after Christmas: Almighty
God, You have poured into our hearts the true Light of Your incarnate Word.
Grant that this Light may shine forth in our lives; through the same Jesus
Christ, Your Son, our Lord, who lives and reigns with You and the Holy Spirit,
one God, now and forever. Amen.
