I know nothing of GOD's timing. It doesn't concern me anymore. But I know that the way we look at stress can FREAKING KILL you! Scientifically, it's not the stress, but the attitude toward it. So embrace it. It's gonna happen. Stoicism can save your life.
When God puts love and compassion in your heart toward someone, He's offering you an opportunity to make a difference in that person's life. You must learn to follow that love. Don't ignore it. Act on it. Somebody needs what you have.
