Confirmation of George Friedrich Spoering

This lovely, old Confirmation certificate was given to me for safekeeping, and I treasure it, not only for its family history connection, but also for its beauty.  George Friedrich Spoering was the youngest brother of my grandmother, Ida.  Born in 1899, he was confirmed in St. John Lutheran Church by Rev. Boomgarden in 1913.  
In the photo of the Spoering family below,he is the young boy in the front row, standing with his arm on his mother's shoulder.

In those days, large, colorful certificates were presented for baptisms, confirmations and weddings held in the church.  This particular certificate says that it was made in Germany and since German services were always held in the Lutheran churches in Henry County back then, the entire certificate is in German.

"In Memory of the Day of Confirmation"
Now Denkspruch...the best translation I could find was maxim or saying or perhaps, verse.
*UPDATE: Thanks to my friend, Kerstin (our Tietje researcher) for her help in the translations on the certificate:
denken = to think
denk = I would say, that is the form of imperativ singular: Think about!(denk, denke, also bedenke)
Spruch = proverb/ saying

A "Denkspruch" is a short sentence, which wants to express/ verbalize a true rule or experience of life.
It wants to make the reader think about or think over something.
 I did not investigate the verses given...maybe some kind German speaker will help on that. 
**UPDATE:
Verse 1:The prophet Jesaja  predicted the crucifixion of Jesus about 700 years before it really happened by the words:
“Christus is wounded because of our misdeeds and he is broken up because of our sins. He bears the punishment, (or: The punishment lies on his shoulder), so that we have peace and we are healed because of his wounds.”

Verse 2: (Song, Author: Benjamin Schmolck (1672 - 1737))
This is the first verse of an old churchsong from Benjamin Schmolck (1672-1737. He was a German theologian; hymn writer and author of devotional literature.
Soul, go to Golgatha,
sit down under Jesus’ cross
and think over, what impulse bids you there, to do penance.
Do you want to be insensible?
Oh, so you are more than stone.

Verse 3, bottom left: „Be faithful up to death, so I will give you the crown of life.”
In former times, this was a very popular Confirmation verse. It is written in the last book of the Bible in a letter from Johannes to his own parish, who suffered because of acute persecution. The existence of the parish was threatened and the members were afraid about their own life. So Johannes said the words, to encourage his people to be faithful up to death, to keep up in believing in God,even if they will lose their life. Then they will get the „crown“, actual you find instead of „crown“ the word „Kranz = wreath“. Maybe you can compare it with a winner, who gets a Victor’s crown. And the price is eternal life. 

George was born on the 14th of August 1899 and was confirmed on the 16th of March 1913 in the Evangelical Lutheran, St. John's Lutheran Church in Deshler, Ohio, by Rev. Boomgarden, Pastor.

The bottom of the certificate holds the impressed seal of the church, St. Johannes.
 Notice the rich coloring of the paper and the images presented, all having symbolism, I'm sure.  At the top are the angelic children around the communion cup, and at the altar is the pastor with the confirmands kneeling and receiving their blessing with adult witnesses of the church watching.  The Last Supper is portrayed at the bottom and in the right, bottom corner is the Dove ascending from the baptismal font.  Even the flowers likely carry symbolism - the grapevine ("I am the vine..."), the wheat (bread of life, separate wheat from chaff...), the poppies (death) and are those forget-me-nots? 

Tell me what else you see in these photos.
