I enjoy gardening; it's wonderful introvert time, and a chance to create a thing of beauty. Once I finish, I find myself liking to just look at the finished product—and subjecting others to photos they might not care about in the least :).
Surely, I could have planted these flowers earlier, but every year I procrastinate. Why is that? I know it will be hard, that's why. (This weekend alone, I spent about 10 hours working in the yard.) It's hard work to create the garden and it takes work to maintain it: weeding, raking, chopping, digging, planting, mulching, watering, etc. And, of course, plants grow during summer; so it tends to be hot, sweaty, grimy work. If you're going to garden you gotta be willing to get your hands (and for that, matter most of your body) dirty; there's really no getting around it.
Much as I would prefer to simply walk in the back yard one morning and have the flower garden waiting, in 42 years I've never seen it happen—I keep waiting. The potential is part of the property but until I put forth effort to "activate" that potential, it will not become reality.
What is true for my garden also was true for the people of Israel. Much as they might have preferred it, they didn't simply walk into to Canaan unopposed. Yes, God led them to the new place and was giving them a new home that was brimming with potential, but they would have to work hard to start turning that potential into reality. Israel still had to overcome considerable obstacles before the land would be truly theirs. In fact, they literally had to fight to take possession of their new home.
