How many there are who imagine that because Jesus paid it all, they need pay nothing, forgetting that the prime object of their salvation was that they should follow in the footsteps of Jesus Christ in bringing back a lost world to God.

Nicholas Ludwig, Count Zinzendorf, was born in Dresden in 1700. He was very much a part of the Pietist movement in Germany, which emphasized personal piety and an emotional component to the religious life. This was in contrast to the state Lutheran Church of the day, which had grown to symbolize a largely intellectual faith centered on belief in specific doctrines. He believed in "heart religion," a personal salvation built on the individual's spiritual relationship with Christ.
Zinzendorf was born into one of the most noble families of Europe. His father died when he was an infant, and he was raised at Gros Hennersdorf, the castle of his influential Pietistic grandmother. Stories abound of his deep faith during childhood. As a young man he struggled with his desire to study for the ministry and the expectation that he would fulfill his hereditary role as a Count. As a teenager at Halle Academy, he and several other young nobles formed a secret society, The Order of the Grain of Mustard Seed. The stated purpose of this order was that the members would use their position and influence to spread the Gospel. As an adult, Zinzendorf later reactivated this adolescent society, and many influential leades of Europe ended up joining the group. A few included the King of Denmark, the Archbishop of Canterbury, and the Archbishop of Paris.
During his Grand Tour (a rite of passage for young aristocrats) Nicolas visited an art museum in Dusseldorf where he saw a Domenico Feti painting titled Ecce Homo, "Behold the Man." It portrayed the crucified Christ with the legend, "This have I done for you - Now what will you do for me?" The young count was profoundly moved while looking at the painting, feeling as if Christ himself was speaking those word to his heart. He vowed that day to dedicate his life in service to Christ.

Frances R. Havergal was staying in the house of a pastor in Germany. In his study there was a picture of the crucified Saviour; underneath which was the motto: "I did this for thee. What hast thou done for me?" It was January 10, 1858. She had come in weary, and sitting down before the picture the Saviour's eyes seemed to rest upon her. She read the words, and the lines of her hymn flashed upon her. She wrote them in pencil on a scrap of paper. Looking them over, she thought them so poor that she tossed them into the stove, but they fell out untouched. Some months after she showed them to her father, who encouraged her to preserve them and wrote the tune "Baca" specially for them.

"I gave My Life for thee,
My precious blood I shed
That thou might'st ransomed be,
And quickened from the dead.
I gave My life for thee:
What hast thou given for Me?

I spent long years for thee,
In weariness and woe,
That an eternity
Of joy thou mightest know.
I spent long years for thee:
Hast thou spent one for Me?

My Father's home of light,
My rainbow circled throne,
I left, for earthly night,
For wanderings sad and lone.
I left it all for thee:
Hast thou left aught for Me?

I suffered much for thee;
More than thy tongue may tell
Of bitterest agony,
To rescue thee from hell.
I suffered much for thee:
What canst thou bear for Me?

And I have brought to thee,
Down from My home above,
Salvation full and free,
My pardon, and My love.
Great gifts I brought to thee:
What hast thou brought to Me?

Oh let thy life be given
Thy years for Him be spent,
World-fetters all be riven,
And joy with suffering blent.
Bring thou thy worthless all:
Follow thy Saviour's call."


"This have I done for you - Now what will you do for me?"
