You must stop from time to time and look at what you're doing in relation to Me and in relation to eternity. Think about what you have planned to do today and ask yourself if it's eternally sound, if it's something that you can take with you when you leave Earth, or if it's something that's going to pass away and be lost.
You must live for the second life, the world beyond, rather than living for this current life, this short time‚ this vapor. When you look at the heavenly vision you're reminded and motivated by what's really important and what's actually worth living for and caring about, and you can set aside what is too petty and meaningless to let into your life or hold you back.
Things tend to snap into perspective when weighed against eternity. And, oh, the comfort it can bring to your heart when you can remember that no matter how tough a battle may seem, your life on Earth is just the tip of the iceberg. Whatever was tough on Earth is not going to be tough in Heaven, and you're going to be so happy that you held on and fought bravely.
