"We shall believe"

1. Alma 9: 2
     2 Who art thou? Suppose ye that we shall believe the testimony of one man, although he should preach unto us that the earth should pass away?
2. Alma 32: 17
     17 Yea, there are many who do say: If thou wilt show unto us a sign from heaven, then we shall know of a surety; then we shall believe.
