"If you keep on biting and devouring each other, watch out or you will be destroyed by each other."We need to make sure that what we say is God honoring and isn't coming from the emotion of the moment. It is better to not say anything than to say something rashly and regret it later. If we don't watch our tongues we will end up like this snake, eating itself.
This especially applies to the Church, if we keep back-biting and gossiping how will we be able to stand? We need to be unified.
"If you have any encouragement from being united with Christ, if any comfort from his love, if any fellowship with the Spirit, if any tenderness and compassion, then make my joy complete by being like-minded, having the same love, being one in spirit and purpose. Do nothing out of selfish ambition or vain conceit, but in humility consider others better than yourselves. Each of you should look not only to your own interests, but also to the interests of others."
