From meteōros (raised up, in mid-air). Literally to be 'up in the air' — hence to be in suspense, to be anxiously uncertain. The root of the English word 'meteor.' Used only once in the NT, in Luke 12:29.
Jesus commands His disciples: 'Do not set your heart on what you will eat or drink; do not worry about it' (Luke 12:29). The image is vivid — anxiety is like being suspended in mid-air with no solid ground beneath you. Jesus offers the antidote: seek the Father's kingdom, and all these things will be given to you. Faith is the solid ground that ends the anxious suspension of unbelief.
