God's man, in the center of God's will, is immortal until God is done with him.
-Dr. David Jeremiah
This is not to say, "Hey, I'm living in God's will and am invincible! Let's go base-jumping!" (video, in case you don't know what base jumping is) It's more of a, "we can rest in confidence." Anything that happens is God's will. I can't escape it, good or bad.
"The LORD is for me;
I will not fear;
What can man do to me?" (Psalm 118:6).
