I am not very far into it, but so far I've found it very helpful. Today I was reading a chapter on self-control and came across these two statements that capture the blessedness of that virtue so well.
"Self-contol is our wall of defense against the enemies of our soul.""We desperately need the grace of self-control to avoid sin's destructive cycles. When we recognize self-contol as the virtue that spares us from sin's negative consequences, we will welcome it eagerly as our friend."
Reading those words made me want to do just that. Welcome self-control as my dear friend.
