2 Corinthians 1:9
But we had the sentence of death in ourselves, that we should not trust in ourselves, but in God which raiseth the dead:
Note 11 at 2Co 1:9: You can't kill a dead man. Paul had already laid down his life and surrendered everything to Jesus. He wasn't living for self, but for Jesus. Therefore, he could not be stopped by death threats.
The reason we get so overwhelmed at times is because we aren't dead to ourselves. As long as "self" is lord of our lives, we will trust in "self." When circumstances go beyond our control, then panic enters. The antidote is to die to self. Then, just like Paul, you can't terrorize a dead man.
