"“Do not let your hearts be troubled. You have faith in God; have faith also in me."
John 14:1
Jesus wants to give us the cure to our ailment. Often our hearts can be troubled, stressed, and depressed simply because we're focused on ourselves and how events and circumstances effects us, and not on Christ. Jesus wants us to know that regardless of what we are going through, we can put our trust in Him and have peace with whatever the outcome is.
Also, Jesus provides a hope of a resurrection and knowing that this life is not it. This life is not perfect and it never will be. But praise God we have a hope of eternity with Him in perfect paradise.
I am currently going through a rough patch in life but it's so comforting to know I have a Savior working it all out behind the scenes and making sure that all things work out for good.
May the peace of Jesus Christ be with you all!
