In 24 months, you will have 24 years worth of spiritual adventures. You will see people change; soften; become more humble, more obedient; have their prayers answered; and come to a knowledge that our message is true.
Let me illustrate with a few stories
Two elders met and taught a professor with credentials from Heidelberg and the Sorbonne. His mind was not open to their message, but the man had to go to the hospital for surgery. While he was recuperating in the hospital, his yard and garden suffered. The two missionaries felt impressed to use their preparation day to mow his lawn, trim the hedge, and weed the flowers. The wife told her husband what they had done. He sent for the elders to come to the hospital, and with tears in his eyes he said, "Never in my entire adult life has anyone ever gone out of his way to do anything for me."
His demeanor changed. He listened to the missionary discussions. Previously skeptical, he now paid rapt attention and visibly became more meek and humble. He prayed for the first time since he was a child, and he received a testimony and was baptized.
Two missionaries asked a new family to kneel in prayer, and the senior companion, not knowing why, asked the husband to move over by his wife and take her hand. He hesitated, and the missionary simply said, "That's what my mom and dad do at home. Please take your wife by the hand."
After they were baptized, the husband and wife tearfully confessed that they were on the verge of divorce when they met the missionaries. The husband had already moved out of the home. He was just there to visit the children when the missionaries appeared. The husband said that as his hand touched his wife's a healing spirit came over them. Love replaced the wounds and the misunderstandings; they forgave each other, and the husband came home.
Another man said that he would not go to church but that his family could go. The missionaries told him that they would always save him a seat right by the door in case he changed his mind. One Sunday he was prompted to go to church even though his family had left without him. From the foyer he could see his family seated with the missionaries and a space at the end of the pew vacant and easily accessible. He entered the little chapel, and his footsteps were heard. The missionaries turned their heads, and when they saw him, tears came to their eyes. After baptism the husband would say, "Never in my life had anyone ever cried out of happiness just to see me enter a room."
Be instruments in his hands.
