Nehemiah 4:10 And Judah said, The strength of the bearers of burdens is decayed, and there is much rubbish; so that we are not able to build the wall.
If we do not get rid of the trash, the rubbish, then we will find that we are unable to work. As we work and serve God we are regularly beset my selfish desires. As I write this I am reminded of how much I think of me and what I want. I want to be appreciated. I want for me and that is rubbish. I pray but often selfishly. I preach but often thinking of how I look. God is not pleased and these things hinder us.
Satan loves for me to think of myself. Satan loves for me to focus on myself and what I am feeling and needing. Satan will destroy me because he will keep this trash front and foremost in my life. I must get rid of the junk if I want to concentrate on the work He has in front of me.
