We know we are moving forward toward spiritual maturity when our lives are centered in God's Word and we are living with a value system of ethics that is based on the Word of God. Our moral behaviors will only be acceptable to God when we constantly judge our decisions by what God's word has taught us. In the apostle Paul's letter to the Corinthians, he says we are to demolish arguments and vain imaginations in our minds, and every idea that sets itself up against the knowledge of Christ. We are to take captive every thought and make it obedient to Christ. We must be ready to punish (stop being a slave to) every ethical wrong standard the world believes. And finally, we must destroy every thought of moral indecency in our minds because we should live our lives to please God and not man (2 Cor. 10:3-6) There is a connection between the soul man and the spiritual man but the Word of God will divide the soul from the spirit. In the book of Hebrews we read, "For the word of God is alive and active. Sharper than any double-edged sword, it penetrates even to dividing soul and spirit, joints and marrow; it judges the thoughts and attitudes of the heart." (Hebrews 4:12)
Coming to Christ and knowing salvation as the Lord gives our entry into the spiritual man. The spiritual man is dormant until we receive the enlightenment from the Holy Spirit. The outward call of the Holy Spirit searches the hearts of all man and speaks into the heart of that man. The outward call now becomes an inward call. That is, we by faith have received the grace that God has given to us that we may call him Lord. The inward call now has awakened the spiritual man in us. Building a Christian conscience begins with receiving the inward call of God in our lives. Walking with God in Christ Jesus as one truly saved is the key to a Christian conscience.
