For Christians, what are some good scriptures in the bible to read when you are going through a difficult trial in your life?

I've only just found your question, and because I am going through difficult trials right now, I would like to share with you some verses that give me comfort:

Psalm 46:1: "God is our refuge and strength, a very present help in trouble."

Isaiah 26:3: "You keep him in perfect peace whose mind is stayed on you, because he trusts you."

“Praise be to the God and Father of our Lord Jesus Christ, the Father of compassion and the God of all comfort, who comforts us in all our troubles, so that we can comfort those in any trouble with the comfort we ourselves receive from God” (2 Corinthians 1:3–4).

In 2 Corinthians 1:3, God is called the “Father of compassion” and the “God of all comfort.” In His mercy and love, God is eager to provide comfort to His children in any and all circumstances. Whatever the trial we face, our Heavenly Father knows the situation and offers comfort as needed. The fact that He is the God of all comfort teaches that all comfort ultimately comes from Him. He is our source of peace and happiness and blessing.
