Believers are caught in a battle between the kingdom of God and the kingdom of darkness, but the Lord has provided everything we need to stand firm against the forces of evil. Why, then, do Christians fail so often and give in to temptation and sin? I think there are a number of reasons.
• We are unaware of the battle. Even if we know about spiritual warfare, during everyday life, it's easy to forget an invisible war is raging around us. Our inattention makes us prime candidates for an attack.
• We are ignorant about the Enemy. Satan will hit us with one scheme after another when we don't recognize his tactics or understand his goals.
• We are untrained for battle. Believers are soldiers whether they want to be or not. God's Word is the training manual that gives instruction for discerning deception, resisting temptation, standing firm in faith, and walking in integrity.
• We allow Satan a foothold. The primary battleground for Christians is the mind. If we begin to listen to the Tempter and consider the benefits of his suggestions, he will gain a foothold into our thoughts, feelings, and desires. Left unchecked, the foothold will become a stronghold, and we'll soon find ourselves mired in sin.
The time to prepare for warfare is now. You cannot be complacent and unaware of your Enemy, or you will become his victim. Begin filling your mind with God's Word, and obediently listen to the Spirit's inner warnings. That's the way to experience the joy of victory in Christ.
