Elder Richard G. Scott of the Quorum of the Twelve Apostles helps answer this question in his general conference talk "Trust in the Lord" (Ensign, Nov. 1995, 16–18).
God knows what He is doing. When we pass through trials for His purposes, we can trust Him to help us.
God's plan is to exalt us so we can return to live with Him.1
Overcoming trials is part of that plan. As we do so, we gain strength, understanding, faith, and trust in God.2
Consider sharing Elder Scott's talk "Trust in the Lord" with someone who is struggling.

In Gethsemane, Jesus Christ set a perfect example of trust when He asked His Father that "if it be possible, let this cup pass from me." But then He said, "Nevertheless not as I will, but as thou wilt" (see Matthew 26:39–44).
