“Hope is a gift of the Spirit. It is a hope that through the Atonement of Jesus Christ and the power of His Resurrection, we shall be raised unto life eternal and this because of our faith in the Savior. This kind of hope is both a principle of promise as well as a commandment, and, as with all commandments, we have the responsibility to make it an active part of our lives and overcome the temptation to lose hope. Hope in our Heavenly Father’s merciful plan of happiness leads to peace, mercy, rejoicing, and gladness. The hope of salvation is like a protective helmet; it is the foundation of our faith and an anchor to our souls.
“We hope in Jesus the Christ, in the goodness of God, in the manifestations of the Holy Spirit, in the knowledge that prayers are heard and answered. Because God has been faithful and kept His promises in the past, we can hope with confidence that God will keep His promises to us in the present and in the future. In times of distress, we can hold tightly to the hope that things will “work together for [our] good” as we follow the counsel of God’s prophets. This type of hope in God, His goodness, and His power refreshes us with courage during difficult challenges and gives strength to those who feel threatened by enclosing walls of fear, doubt, and despair.”
Dieter F. Uchtdorf, “The Infinite Power of Hope,” Ensign, Nov 2008, 21–24

I am sorry to hear about this tragedy. Our prayers will be with your family.
How comforting to have the knowledge of the restored gospel of Jesus Christ and the sealing powers found in the temples, otherwise tragedies such as this would be unbearable.
May God bless you during this difficult time.

Thank you for sharing this. I have been thinking a lot about the passing of my dad last mother's day and then my cousin's wife over this past weekend. It is more important than ever to believe in the gospel of hope when we lose someone. I am so sorry for your family.
