1 Peter 2:5
…you also, as living stones, are being built up a spiritual house, a holy priesthood, to offer up spiritual sacrifices acceptable to God through Jesus Christ.
One of the primary goals for the believer is to become spiritual (dominated by our spirit man, the real you), not carnal (dominated by our flesh). You are a spirit, you have a soul, and you live in a body. Man has learned how to develop his body and his soul, but has done very little to develop the spirit man within.
For example athletes have worked hard to develop their bodies to win athletic competitions. Many have also learned to develop the mind through education, but few have developed the most important part of man, their spirit. When your spirit is dominating instead of your flesh you are not ruled by your feelings. You can also be easily led by God in knowing and walking out His will, for He leads us through our spirit man within. To develop your spirit man you need to:
- Meditate on the Word of God.
- Practice the Word.
- Give the Word first place.
- Obey your conscience (the voice of your spirit).
- Pray in the Spirit.
- Walk in love.
Do these things and you will grow spiritually. As you do the old fleshly nature will no longer rule you and you will be led by your spirit man, the real you on the inside.
