My dad was a disciplined soldier in the U.S. Army.
Shalom,
As a believer, you are a soldier in the Body of Christ. Remember, our weapons are not natural weapons, but supernatural weapons. Our Heavenly Father has given us the Name of Jesus, the Word of God, and we are Blood Covenant partners with Him. Everything we have belongs to Him and everything He has belongs to us. It's up to each believer to choose what is necessary to be a disciplined member of the Body of Christ.
Have a good day,
Bill
