Extinguishing joy is clearly a primary demonic objective of these times. The best way to counter the seemingly never-ending onslaught is to aspire to be "in" joy every day.
Being "in" joy is not merely about comforts, amusements, distractions, and pleasures. Though these things may spark or stoke joy, being "in" joy transcends the dictum to "enjoy".
At its core, I interpret being "in" joy as an exercise in thinking that leads to an interchange between the Divine and the divine within us. It presents an opportunity to commune with the very essence of the Creator and His Creation.
Above all else, joy is a testament to the reality of God and the presence of God's love. Being "in" joy is to be fully immersed in that reality and that presence, even if it lasts but a moment each day.
Every moment we spend "in" joy feels like a century to the enemy . . . which is exactly as it should be and precisely why it matters.
