"Savior of the Nations, Come"

Martin Luther's, "Savior of the Nations, Come", as I see it, makes an excellent appeal of logos and ethos in regards to the Lord's virgin birth and his victory over sin.  We can first see evidence of logos within the beginning stanzas, particularly in the second stanza, by showing the importance and meaning behind the virgin birth.  Not being born of a virgin would simply undermine Christ's divinity, and as Luther states, "Was the Word of God made flesh--Woman's Offspring, pure and fresh. Wondrous birth! O wondrous Child."  The virgin birth affirms Jesus' life of purity and helps show that Christ was more than human.  In the few remaining stanzas, Luther begins to appeal to the reader's emotions by illustrating Jesus' conquer over death, ultimately saving man.  An excellent verse that I thought said it best was, "Thou, the Father's only Son, Hast o'er sin the victory won."  By dying on the cross, we are saved and, for that, we owe God eternal praise.  "Praise to God the Spirit be ever and eternally."  Luther's hymn, in a nutshell, nicely describes Jesus' great triumph over sin and is a great example as to how grateful we should be for his sacrifice.
