The human mind is capable of receiving many impressions that can last a long time. The impression that our human computer receives and registers are recorded either consciously and/ or subconsciously. During the course of a normal day, we receive thousands of impressions upon our mind.
These impressions are recorded and very often determine who we are in any particular situation. "As a man thinketh in his heart, so is he"(Proverbs 3:7). We as Christians are to be careful to regulate this computer by the Holy Spirit and the Word of God. All of the impressions that we receive are to be regulated by God through us. The dust of the world that has accumulated during the course of a day is to be washed away by the power of the Living Word, so that we have mental renewal ( John 13:10; Ephesians 4:23). The condemnation of all of our yesterdays is to be purged by the Blood of the Lamb (Hebrews 9:14) through faith.
The frontal lobe activity of our mind casts down every thought and high thing that exalts itself against the knowledge of God through obedience (2 Corinthians 10:4-5), letting the Word of Christ dwell in us richly (Colossians 3:16). Through the power of the Holy Spirit and the flow of God's Word, we become utilized by God's thoughts. No longer are we simply the by-product of thousands of everyday projections, opinions, or emotional feelings, but now through the discipline of the life of God we become eternally purposed.
