You remain joyful by sitting alone on a park bench or in an omnibus that’s half-full. As you allow the breeze to speed over you in the former, or the bus to speed through the city in the latter, you may observe. Looking out and watching humanity pass by is extremely beautiful. How can you lack a sense of joy when you see all the cars sailing past you on the highway like a grand fleet? You can almost feel the progression of history; the long crawl of God’s plan being unfolded, as it were. This is pure joy!
Merely being with a human being you trust completely and are loyal to until death is joy. When you look into your best friend’s eyes and see him smiling at you with the most earnest and honest smile in the world, you become joyful. You see our Lord Jesus Christ in each man’s smile, and even in each man’s frown! I think you simply need to connect with one human being, the manly nature of Jesus. When this is accomplished, all other human beings seem to shine with an aura.
Read the Gospels, and think of them quietly as you are walking through the city on a golden afternoon, the last winds of noon caressing your skin. How can you see the swaying nations of trees and the innocent kingdoms of animals flitting through the branches and public gardens, and not feel joy? Our Lord created this world with intensity, and joy can be found everywhere! Listen to Haydn’s major-key symphonies, sit down with your most intimate friend to talk about God… whatever! Life is glorious, and though we are in a great war, there are still bastions untouched by the scourge of Hell - preserved by God for our joy.
