“My child, I’ll willingly let you go.  You’ll make a fine missionary, and I’m sure God will be with you.”

“Thank you, Mother,” said twenty-six-year-old Mary.  “I know God will be with me and will make me strong and brave to serve Him.”

Mother Slessor was very happy.  There was going to be a missionary in the family after all.  But there were some people who did not agree with Mother Slessor.  They shook their heads in doubt.  Others thought Mary was very foolish to risk her life in that way.

“You’re doing real well at the factory,” said one of them.  “And you’re doing missionary work right down there at the mission.  Why rush away to those people way off in Africa?  Seems to me missionary work ought to begin at home.”

“Yes,” said Mary, “it should begin there, but not end there.  There are some who cannot go to Africa.  They can do the work at home.  If God lets me, I want to take His Word to those people who have never heard of Him or His love.”

The next year, 1875, Mary offered herself to the Foreign Mission Board of her church.  She asked to be sent to Calabar.  Then she waited.  Waiting is hard sometimes.  Mary had to wait until the Board had a meeting.  Then when the meeting was over, she had to wait for the secretary of the Board of Foreign Missions to write her a letter.  Early in 1876 the letter came.  How excited Mary was!  Her hands shook as she tried to open the letter.  Had they accepted her offer or refused it?

“Mary dear,” said her mother, “you are so nervous, you had better let me open that letter.”

“I’ll manage, Mother,” said Mary.  She finally got it open, and she read: 

Dear Miss Slessor, I take great pleasure in informing you that the Board of Foreign Missions accepts your offer to serve as a missionary, and you have been appointed teacher to Calabar.  You will continue your studies for the teaching profession at Dundee.  May God richly bless you in His service.

“Oh, Mother, I’m accepted!  They’re going to send me to Calabar!”

“Praise God from whom all blessings flow,” said Mother Slessor.  “That is wonderful news indeed.  To Calabar!  Oh, I’m so happy I could shout for joy!”

In March another letter came.  This letter told her that she was to spend three months at a teachers’ college in Edinburgh.  All Mary’s friends in Dundee gathered at the train as she got ready to leave for Edinburgh.

“Come, Mary,” said Duncan, the tough boy from the slums, who was now a grown man and a faithful worker at the mission, “give us a speech.”

“I can’t make a speech,” said Mary, “but I’ll just ask you this:  Pray for me.”

While Mary was at the school in Edinburgh, some of the other girls she met there tried to talk her out of being a missionary.  They did not want her to go off to Africa where there were wild animals and man-eating heathen, and all kinds of terrible sicknesses.
