When you have reached it here, you have learned a few things. One is that there is a sense of harmony when you are with other believers. This is really the only thing that I crave besides communion with the LORD... communion with the saints.
But what if there is resistance in that harmony that you keep running into? This saint is simply not part of your church. They are struggling or thriving in the LORD but you don't need to interact with them. They really aren't good for you.
The person in my life that I am struggling with has so many other gods and spirits on them that I am overwhelmed when I am around them. They make me feel anxious even though they are trying to be kind to me.
The wisdom they are sharing is not for me, nor for you.
