But understand this: If the owner of the house had known at what hour the thief was coming, he would not have let his house be broken into (Luke 12:39).

What are the times when you and I are most vulnerable to being caught off guard by the enemy of our souls? One of those times is just after you've had a great victory. Consider Jesus when he was baptized and was about to begin His public ministry. He was taken away into the dessert to be tempted by Satan.

Leisure time is another place in which Satan seeks to take us off our normal routine of personal quiet times. In the normal routine of life our senses are tuned to the need to draw upon God's Spirit to see us through the activities of each day. However, when we get away from our routine and go on vacation, we can often drop these routines. We wrongfully think that we do not need to spend time with the Lord during leisure times. This is a grave mistake. The vacation becomes a test of character. During vacations we turn freely to what we love most. It reveals to us what is at the core of our existence.

A teacher in a large school reportedly said, "The greatest difficulty we encounter is the summer vacation. Just when we have brought a student to a certain discipline and place in their study habits, we lose him; when he comes back we have to begin all over again." It is the same in our spiritual lives. It only takes a small crack in the door of our heart to lose our spiritual focus.

This summer be on guard when times of retreat are made available to you. Use these times for spiritual refreshment, not just physical refreshment. And you will keep the thief from entering your house.
