"Why don't I become a missionary?" Mary asked herself as she worked the looms in the factory. "Can I leave my home? Does Mother still need my help? Susan and Janie are working now. They could get along without me. But will I be brave enough? There are tropical jungles, and black men who eat people. There are wild animals, sicknesses, and death. God can make me brave to face all of these things."
Mary prayed, "O God, if it is Your will, let me go as a missionary to Calabar. Let me be a teacher to teach these black people the story of salvation. You have commanded us, Your disciples, to carry the Gospel to the farthest parts of the earth. Use me, O Lord, to help carry it to Calabar. Hear me, for the sake of Jesus, my Saviour."
It was 1874. The news flashed around the world: "Livingstone is dead." The great missionary had died on his knees in Africa. Everywhere people were talking of this great man who had given his life to tell the people of Africa about the Saviour. Mary made up her mind! She must go to Calabar! But what would her mother say? And if her mother agreed, would her church send her out to that field? Mary went to her mother.
"I want to offer myself as a missionary," said Mary Slessor to her mother. "Are you willing?"
"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?
