"But understand this: If the owner of the house had known at what time of night the thief was coming, he would have kept watch and would not have let his house be broken into." -Matthew 24:43

Imagine if I am the owner of this house (my heart, soul, and mind) and the thief is sins I commit. Without doubt if I knew exactly when temptations and desires would crawl into me, I would more likely resist them. While I do not know when the thief will sneak in, I have been warned the thief will come.

Always be vigilant against possible temptations
 so my heart, soul, and mind will not be robbed.
