Typical responses to the falling of a comrade vary from a shake of the head, to pity, to disgust, to ignoring the fall. But it ought not to be so among believers.
The go to response for an overtaken brother or sister must be a spiritual one. In meekness, those sensitive to the situation, led by the Spirit, bathed in prayer and fully considering his or her own frailty, must respond in love and compassion, never leaving a fallen brother or sister in arms to languish on the battlefield. The fallen must be hurried to a M*A*S*H unit, which is the local church. There to be restored to spiritual health.
Thus fulfills the law of Christ, which is to love one another as Christ has loved us.
