Mission Story:

There was an Elder in the South German Mission that had worse German than me. It was so bad that even I could hear the mistakes. But he had converts nonetheless. One particular Sister he taught was an interpreter by profession and spoke English as well as any missionary. Interestingly enough the Sister preferred to be taught in German even though her English was better than ours and obviously her German was quantum leaps beyond our abilities. The reason: the spirit was stronger in German.

It has been said that missionaries do not convert, the spirit does. The following is a quote from Brigham Young on this topic.

“If a man speaks by the power of God, it is little matter to me what his words are, or the language he uses. If I understand the spirit of it, that is the way I find ‘Mormonism’ to be true. The brethren who came to preach the Gospel to me, I could easily out-talk them, though I had never preached; but their testimony was like fire in bones; I understood the spirit of their preaching; I received that spirit; it was light, intelligence, power, and truth, and it bore witness to my spirit, and that was enough for me. I have received it, and I have tried to improve upon it.” (Journal of Discourses, vol 9, p 141)

That should be enough to encourage the most timid of us to bear testimony when moved by the spirit. It need not be boisterous or condescending but a simple statement of belief presented lovingly as directed by the spirit.
