John 14:27 Peace I leave with you, My peace I give to you; not as the world gives do I give to you. Let not your heart be troubled, neither let it be afraid.
When Jesus said He was giving us peace to live within it was not a nice cosy cottage in the middle of nowhere but a spiritual state we would be in whilst the Holy Spirit came to live with us.
Jesus wants us to be cared for from the inside and not just physically and emotionally. God wants us to be able to experience the peace only he can give and to live with it while we live in our troubled lives.
We may still face hardships we struggle with, but we can always know God is with us and caring for us from the inside!
