From my window I can see a 1,700-meter hill called the Cerro del Borrego or “Hill of the Sheep.” In 1862, the French army invaded Mexico. While the enemy camped in the central park of Orizaba, the Mexican army established its position at the top of the hill. However, the Mexican general neglected to guard access to the top. While the Mexican troops were sleeping, the French attacked and killed 2,000 of them.

This reminds me of another hill, the Mount of Olives, and the garden at its foot where a group of disciples fell asleep. Jesus rebuked them, saying, “Watch and pray so that you will not fall into temptation. The spirit is willing, but the flesh is weak” (Mark 14:38).

How easy it is to sleep or become careless in our Christian walk. Temptation strikes when we are most vulnerable. When we neglect certain areas of our spiritual lives—such as prayer and Bible study—we become drowsy and let our guard down, making us easy targets for our enemy, Satan, to strike (1 Peter 5:8).

We need to be alert to the possibilities of an attack and pray to maintain vigilance. If we remain watchful and pray—for ourselves and for others—the Spirit will enable us to resist temptation.
