It is therefore the believer's soul which is the target for the enemy's missiles. Human viewpoint in the soul of the believer is our enemy's goal. The positive believer must garrison his soul continually with residual truth. This verse points to the transition of divine power from the dispensation of the hypostatic union to the church age. A divine mental attitude uses problem solving devices rather than defense mechanisms.
Any human solution is based on human reaction no matter how nicely it is doctored up.
If Satan can get us to think via human viewpoint we are not appropriating divine power and divine solutions. It is therefore very important for the evil one to attack our system of thinking since from our thinking comes our motivation and from our motivation comes our decisions and from our decisions comes our lifestyle. Satan attacks every facade of the word of God starting with the gospel to the forty things given at salvation to the grace and word of God to eternal security and the spiritual skills. The enmity factor against the believer in Christ is ever present and increases as our faith increases. Satan hates believers in Christ and he will do everything in his power to hinder the believer's advance in the spiritual realm.
