"And hope does not put us to shame, because God’s love has been poured out into our hearts through the Holy Spirit, who has been given to us." (Romans 5:5)
Every Christian is bi-lingual, although none are fully fluent while below heaven and above ground. The mother tongue is all about what we know and learn in the earth through the senses, which is temporal and temporary. The second tongue is learned from heaven.
For instance, take the word hope. The mother tongue definition of hope is a longing for something that is desired, and which is perceived to be better than something else. The realization of that hope is tenuous at best.
The second tongue defines hope (using the enlightenment of God's communication) as the supernatural grace that allows one to fully expect the good of God's promises, when those promises have been fully earned (by Christ) but not yet fully realized (with Christ above). The realization of heavenly hope is certain and eternal. In Christ, one is never below hope as long as above ground, and never above hope as long as below heaven.
Progressive definition of words in the second tongue reveals more connection between heaven and earth, just as climbing a mountain exposes a broader vista of surroundings. The higher the sun rises the more it clears the air: so, the rising of Christian hope.
