18 Within the midst of everything, be continuously giving thanks (or: In union with all people, be habitually expressing the goodness of grace and the well-being from favor), for this is God's intent (will, purpose) unto you in Christ Jesus (or: [proceeding] into the midst of you folks, in union with [the] Anointed Jesus).
