In talking about the one anothers, most of the focus usually falls on what we should do for others. I suppose this makes sense. However, we also need to realize that we must allow others to do for us. The one anothering is a two way street.
I'm not suggesting that we treat others well because they treat us well. We carry out the one anothers out of joyful obedience to Christ. However, we also need to be willing to accept one anothering from our brothers and sisters in Christ. When we accept their one anothering of us, we do them a service. It provides them with the opportunity to joyfully obey Christ.
These is a sort of reciprocal nature to all this. We all grow up together in Christ as we serve one another. We help others grow by one anothering together. This involves both giving and receiving. If we only focus on the giving, we end up inadvertently hurting both ourselves and others.
One anothering is critical to the life of the church. We all need to be involved in it. When we share with each other in this way, God is honored and we all grow closer to him.
