We all have those kinds of days. That is a part of living in a fallen world. We deal daily with the effects of sin and corruption - from both us and others. But there is something only recently that I have begun considering, largely thanks to Randy Alcorn's paradigm-shifting book, Heaven. It is this fact:
Your bad day is a fragment of a drop in the bucket of eternity and a time is coming when you will never have a bad day again.
In the New Heavens and New Earth, for the Christian, eternal "best days ever" await us.
Days when we won't wake up grumpy from too little sleep.
Days when we won't get frustrated at anything.
Days when we won't come home and cry from exhaustion.
Days when we won't work at a job we hate.
Days when we will have a perfect relationship with food and our body.
Days when we won't ever fake happy; we'll just be happy.
Days when no one will ever slander again
Days with no headaches, no sore throats, no back pains.
Days when gossip will no longer exist.
Days when we get to sit in the presence of God and bask in His beauty.
Days that will only be good days.
So on your bad day, as you're lying in bed at 5:01, reflecting on the lousiness that was your day, think about Heaven. Think about how wondrously, gloriously perfect your life will be one day. How endlessly fun, with endlessly delicious food, and endlessly exciting adventures, and endlessly dream jobs. And no sin.
These thoughts should dissipate your ill will, anger, frustration before you know it. They will also readjust your priorities. God has placed you where you are right now for a specific reason. Don't waste it stewing on the bad; keep your eyes fixated on the end - the everlastingly good - and use that to motivate you to serve your time here well.
