John 16:33

“These things I have spoken to you, so that in Me you may have peace. In the world you have tribulation, but take courage; I have overcome the world.”

How does Jesus become the Game Changer during personal trials to one who is committed to Him?

Jesus has already supplied salvation for all who believe, what is where peace comes from.  The world will fail us every time, but Jesus will finish the work in us (Philippians 1:6)
