One of the girdles to use as a Christian soldier is truth, and Jesus is the Truth. Every Christian soldier must live by the truth of the Word of God. When Jesus came face to face with the devil in the wilderness, the devil was unable to bring anything against Him. In boxing there are three major blows: the jab, the hook and the uppercut. The ultimate goal of any boxer who is in the ring is to hit the head of the opponent. While the opponent is making efforts to see that his head is properly covered against the punches of the opponent, his stomach is exposed and the boxer throws the hook on the stomach. Once the stomach is affected, the opponent tilts forward and the boxer gives the uppercut because he now has access to the head. The spiritual implication of this is that the enemy concentrates on the weak points of a Christian soldier. This is the strategy he applies in dealing with many Christians. The devil has got you the moment he discovers your weak point. Therefore, the easiest way to win the battle against the enemy is to win the battle against yourself.
Let there be a separation between you and those things the enemy can use to condemn you. Don't ever allow the devil to bring you into captivity. You have to keep your body and bring it into subjection. This you can do by crying to the One who has recruited you as a soldier, to help you win the battle over yourself. This battle is not the type you win at once. The flesh will always try to rise again, but you have to continue to fight so that you can maintain your victory. The person, who will win a race will only be crowned if he runs according to the rules. Therefore, you need to live holy. External forces intend to slow you down so that you don't get to the finish line, some may try to stop or pull you back, but what is inside of you should be strong enough to overcome every resistance. You cannot afford to stop running until you are called up into glory because the devil will never take a break. Endure unto the end.
"But he that shall endure unto the end, the same shall be saved" Matthew 24:13

It is not the one who was leading at the beginning that gets the crown but the one that leads to the end. You need to be disciplined as a Christian soldier. Without discipline, one will soon become an ex-champion. The Christian soldier must not allow the lusts of the flesh to distract him from the race to heaven.
"For he that soweth to his flesh shall of the flesh reap corruption; but he that soweth to the spirit shall of the spirit reap life everlasting" Galatians 6:7-8.
