One thing I enjoy about camping is building a fire. I have enjoyed it ever since being a Boy Scout and learning how to build one. As you probably know when a fire starts to die, it only needs to be stirred a bit, just to get the flames going again. Believers need stirred just like a fire does.
This second epistle, beloved, I now write unto you; in both which I stir up your pure minds by way of remembrance: (2 Peter 3:1)
If you want to help believers, stir up their minds to remember God’s word and how the Lord has worked in their lives. Some may need rebuked and others may required a reproof, but by far, the majority need only to be stirred. A loving Christian has no problem with stirring up people. Don’t be quick to think that struggling people need to be rebuked. Their fire of faith may be dwindling low, but a simple stirring of their remembrance about God and what he has done for them will stoke their flames of faith. Be an encourager. The Lord knows, we have enough rebukers in the world.
