The Windows of Heaven (1963)

As 85-year-old President Lorenzo Snow struggles to vanquish the two million dollar indebtedness of the Mormon church in 1899, he feels inspired to journey from Salt Lake City by train and carriage to St. George in southern Utah. Along the way he witnesses the effects of severe drought. The next day, in the St. George Tabernacle, he receives inspiration that by paying tithing, the "windows of heaven" will open, pouring out blessings. He promises the people that they can plant crops and rain will come, then continues to preach tithing as he returns home where he awaits favorable weather reports from St. George.
