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 loader is a heavy equipment machine used in construction to move aside or load materials such as asphalt, demolition debris, dirt, snow, feed, gravel, logs, raw minerals, recycled material, rock, sand, woodchips, etc. into or onto another type of machinery. There are many types of loader, which, depending on design and application, are called by various names, including bucket loader, front loader, front-end loader, payloader, scoop, shovel, skip loader, wheel loader, or skid-steer.
