I do not accept the fact that conditions that prevent people from attaining their eternal destiny were born into them without any ability to control. That is contrary to the Plan of Salvation, and it is contrary to the justice and mercy of God. It's contrary to the whole teaching of the Gospel of Jesus Christ, which expresses the truth that by or through the power and mercy of Jesus Christ we will have the strength to do all things. That includes resisting temptation. That includes dealing with things that we're born with, including disfigurements, or mental or physical incapacities.
The most powerful teaching of children is by the example of their parents.
When we give thanks in all things, we see hardships and adversities in the context of the purpose of life... We are meant to learn and grow through opposition, through meeting our challenges, and through teaching others to do the same... the Lord will not only consecrate our afflictions for our gain, but He will use them to bless the lives of countless others.
I testify of our Savior, Jesus Christ, whose teachings and example we seek to follow. He invites all of us who are heavy laden to come unto Him, to learn of Him, to follow Him, and thus to find rest to our souls.
Every teaching position, every missionary position can be held by single people. We welcome to that kind of service people who are struggling with any kind of temptation when the struggle is a good struggle and they are living so as to be appropriate teachers, or missionaries, or whatever the calling may be.
It seems to me that a Latter-day Saint parent has a responsibility in love and gentleness to affirm the teaching of the Lord through His prophets that the course of action he is about to embark upon is sinful.
Motive is also important in our quest for knowledge and in the questioning that accompanies it. In commenting on our duty to educate for eternity, Eugene England writes: Teaching or learning - with the Spirit of God simply means (though it is not simple) that we are doing so with an eye single to eternal, not worldly, values, with an eye single to lasting development of the mind and spirit and to useful service to others, especially to aid in their lasting development of mind and spirit.
