The poem in 11-13 might have been a song. It is full of hope and promise. I died with Jesus who was crucified. I will live again in paradise forever and ever.
I have not lost faith and endured much. I will reign with him.
Jesus will never disown me. Even if I falter, worry, and doubt he will remain faithful to me. I am in Christ. Christ is in me. I am a part of him. He is a part of me. He will never leave me nor forsake me.
All these are guarantees. When hard times come it does not mean that Jesus gave up on me nor forsaken me. Paul was in chains in a dark damp prison. He professed these truths.
