Watch, stand fast in the faith, be brave, be strong. 1 Corinthians 16:13 (NKJV)
Alertness to the strategy and presence of the enemy is always a fundamental part of winning a war, including the spiritual war Christians fight against the forces of the devil, the world, and SIN. Alertness is dulled by pride or self-reliance. The more confident you are in your abilities, the more complacent you are about sin and the less attentive you are to the enemy’s efforts. Do you know that you wake up to a spiritual war each morning? Are you aware that the power of the evil one is set against you?
Simply stepping out into the day with a smile and a hearty breakfast may make you feel good but does not prepare you for spiritual combat. Alertness begins with awareness of the conflict and the identity of the enemy. Steeled against his schemes, you will not be caught by surprise.
