God has given us moral laws and physical laws. Examples of moral laws are the Ten Commandments and The Beatitudes. An example of a physical law is the law of gravity, that is to say, what goes up must come down. There are many more subtle physical laws that you discover just by living, for example if you drop a raw egg on asphalt it will break. Now if you were to drop that egg, expecting God to act to keep it from breaking, you would be putting God to the test.
Parents are very careful with young children because the kids lack knowledge of many physical laws.
We try to keep toddlers from putting objects in electrical outlets, and in the deep south, we make sure toddlers don't fall into fire ant nests. If you were baby sitting a toddler, and you were to turn that toddler loose in a yard full of fire ant hills, expecting God to act to keep that toddler safe, you would be putting God to the test. Once you get well beyond toddler age, you are expected to anticipate physical challenges on your own and to prepare for them. For example, if you are likely to sunburn at the pool or water-park, you are expected to think ahead and bring sunscreen. Similarly, if you are allergic to poison oak or poison ivy, it is not a good idea to go for a hike in the woods wearing sandals and short pants.
