…how much more shall the blood of Christ, who through the eternal Spirit offered Himself without spot to God, cleanse your conscience from dead works to serve the living God?
When a person is born again they receive a brand new spirit within for they are cleansed of the old spirit man. The voice of our spirit man is the conscience. That inward knowing deep down inside. When you are born again the conscience is therefore also cleansed because you have a new spirit. Our conscience, this inward knowing, is how God leads us for the Holy Spirit bears witness with our spirit man.
If we will learn to listen to this inward witness we can follow God’s leading for our lives. To do this we need to live in God’s Word for the Holy Spirit will always lead us in line with the Word of God. God’s Word is also one of the ways we nourish and strengthen our spirit man. Just as the natural body needs nourishment and exercise to stay healthy, our spirit man needs to be nourished but also exercised.
There are many different exercises you can do to develop the body as there are different ways to exercise your spirit man. The best way to do so is to practice walking in the fruit of the spirit. Practice walking in love, joy, peace, longsuffering, kindness, goodness, faithfulness, gentleness, and self-control. As you feed on the word and practice the fruit of the spirit you can become more aware of your spirit man and learn to know through your conscience God’s direction for your life.
