The big idea of the sermon ought to match closely with the big idea of the text. Steven Matthewson, in his book The Art of Preaching Old Testament Narrative, counsels a progression in thinking about the big idea, beginning with the exegetical idea, building toward a theological idea, and ultimately a preaching or homiletic idea.
Loader (equipment) - Description. 1  A loader is a type of tractor, usually wheeled, sometimes on tracks, that has a front-mounted square wide bucket connected to the end of two booms (arms) to scoop up loose material from the ground, such as dirt, sand or gravel, and move it from one place to another without pushing the material across the ground.
A lot of people only see the loader number on the tractor because the loader covers up the tractor numbers. This is common, donât worry if youâve made that mistake. The loader numbers are the easiest to figure out. Basically itâs LA which stands for Loader, then the lift capacity in kilograms.
