"Come unto Christ, and be perfected in him, ... deny yourselves of all ungodliness, and love God with all your might, mind and strength, ... that by his grace ye may be perfect in Christ." I know that the plan of happiness can lift and bless those who live it anywhere. On Christmas Eve 37 years ago, in the light of a full moon, I climbed a small hill in the isolated village of Quiriza, Bolivia. Four young elders and I had spent the day crossing over a mountain pass on a treacherous road. Then we struggled up a riverbed to see if the teachings of the Savior would help a destitute people. What we saw that day was discouraging--undernourished children, adults subsisting on meager crops, some with eyes glazed from seeking refuge with alcohol and drugs. I looked at the tiny, barren village below: a cluster of adobe thatched-roof houses beaten by the harsh environment. There was no electricity, telephone, running water, roads, proper sanitation, nor doctors there. It seemed so hopeless. Yet a solemn prayer confirmed that we should be there. We found a humble people who embraced the restored gospel with determination to live it. They did that under harsh conditions where severe poverty, alcohol, drugs, witchcraft, and immorality were in plentiful supply. Under the guidance of exceptional missionaries, the people learned to work hard to cultivate the fields. They produced a harvest of nutritious vegetables and raised rabbits for better protein. But the best lessons came from beloved missionaries who taught them of a God who love them, of a Savior who gave His life that they might succeed. Their physical appearance began to change. The light of truth radiated from their happy faces. As devoted, loving emissaries of the Lord, missionaries patiently taught truth to a willing people. Wives and husbands learned how to live in harmony, teach truth to their children, pray, and sense guidance of the Spirit. The youth learned most quickly. They became obedient to the light of truth taught by the missionaries and in time by their own parents. Through their faith and obedience, I have seen how in one generation youth baptized in that village have overcome a seemingly hopeless future. Some have been missionaries, graduated from universities, and been sealed in the temple. Through their diligence and obedience, they have found purpose and success in life despite an early harsh physical and evil-saturated environment. If it can be done in Quiriza, Bolivia, it can be done anywhere.
