Second, sometimes God will use a Bible verse out of context in a new way to speak to your heart. Hey, that's okay. He can do that! It is His Word. He will never use it out of context (and we shouldn't either) that contradicts who He is, but He will use it creatively in your life if you let Him.
Finally, to the verse you need to know if you ever deal with mental health issues (and that can be any of us -- some of us have chronic mental health issues, but all of us can get acute mental health issues): Acts 16:28 says, "Don't harm yourself! We are all here!"
I encourage you to read that chapter to see what the story is behind that verse, but it is a verse we need to remember when depression hits or we feel alone or we feel like we are worthless or we feel we don't matter or we are tempted to self-harm. You are never alone! Never! Even when there are no people around you (or if they are around you and you can't connect), Jesus is right beside you loving you. The Father is calling to you -- Come Home. The Spirit is praying for you when you can't pray for yourself. "Don't harm yourself! We are all here!"
The enemy loves to isolate each of us to make us feel no one understands; to make us feel no one cares; to make us feel that this world doesn't need us; that people don't need us; that we are a detriment to people. All of these statements are LIES!
You have great purpose because God created you to be in relationship with Him. He wants to hang out with you. And He also will give you tasks to do that will bless you and others and share His love with the world. You are the only one who can be you. Memorize Acts 16:28 (Don't harm yourself! We are all here!). Keep it in your mind for those times when lies fill your mind. It is a weapon of self preservation. Not only are there people who love you and God loves you, there are past Believers cheering you on to run this race called life with all your heart and mind and soul and strength. I love how The Message Translation says Hebrews 12:1: "Do you see what this means -- all these pioneers who blazed teh way, all these veterans cheering us on? It means we'd better get on with it. Strip down start running -- and never quit! No extra spiritual fat, no parasitic sin."
The NASB says it like this: "Therefore, since we have so great a cloud of witnesses surrounding us let us also lay aside every encumbrance, and the sin which so easily entangles us, and let us run with endurance the race that is set before us,"
Run, run, run! Live this life fully and wildly and exuberantly and joyously for Jesus!
