Toughness to God's soldier is the ability to obey in a world of disobedience, to exchange what he sees with his eyes for that which he sees with his heart, to be true to the truth from the obvious to the subtle, whatever the effect upon his earth phase. The heart and mind of a soldier is so set upon the outcome of the battle that his desire for personal recognition is secondary. He has learned that he is more powerful as an obscure part of a united force than as a prominent individual on his own. People united share each others strengths and strengthen each others weaknesses. The actions taken as a member of a team are immensely more effective than the attention-seeking activities of independent movement.
Love makes persons want others to be a part of their work.
A Christian loves his brothers and sisters. This love for God and fellow Christians and this understanding of the superiority of united effort causes the Christian soldier to sacrifice self-interest that harmony may be achieved. As Christians all hear from the same God and judge and say the same thing, divisions cease, and the world is presented with persuasive beauty of the body of Christ. Skill 2 Tim. To a soldier his skill is valuable not only for his own self-esteem and his own preservation, but as a tool for the battle.
