The phrase, "restoration," which is only used in the Psalms, in the Bible. It is found in Psalm 23:3, which says, "He restores my soul." The word restore means "to repair, renovate, or return to former condition."
For those struggling Christians, I would recommend praying for restoration. If your soul is not restored immediately, it may not be God's Will at that moment: God knows our lives, he knows everything about us, so he knows if restoration will help us at that particular moment, because he's our Father, he wants what is best for us in the long-run.
How can we know how to restore our soul? God has given us the answers in the Word of God - The Bible. (2nd Timothy 3:16-17) While there are all many different kinds of books, written by men offering worldly wisdom, only God’s Word is truly capable of restoring our soul and giving us hope in times of distress.
Restoring the soul is ONLY possible for those whose souls have been redeemed - saved, through Jesus Christ. In Matthew 28:11, Jesus promises this: "Come to me, all you who are weary and burdened, and I will give you rest." Many take this promise to mean that there will never be trouble in life.
But Jesus did not say it would bu full rest in this life. He wants us to turn as many people as we can to him, because he is not willing that any should perish, but that all should turn to Jesus and be saved. What Jesus promises is rest after we "die." The moment you die, if you have accepted Jesus as the only one who can save you, you will blink, and your next conscious thought will be in Heaven.
However. If you have not accepted him as your savior, since he is the only way to get to heaven, you will not be going there. Thankfully, God provides for us when we face discouragement, trials and tribulation, as well as temptations. God has given us three primary sources of strength and encouragement.
