In the New System we will have a completely different way of dressing. You never see any of the brothers in suits in the artist conceptions of the New System. Everyone has their own style of clothes in the pictures. But for now we have to show the world that professional persona so they know we take things seriously
Tell me about it, not even married couples are allowed to hold hands or embrace, (side embrace) each other while praying in a kingdom hall. Talk about silly rules:
Some marriage mates might discreetly hold hands, but if they embraced each other during public prayer, those who got a glimpse of such conduct might be stumbled. They might think or get the impression that the couple was focusing on their romantic relationship instead of reverence for Jehovah. Out of deep respect for him, let us therefore “do all things for God’s glory” and avoid conduct that could distract, shock, or stumble anyone.
