There are people who make detailed plans and thorough preparations for every matter. Such people tend to have a lot of worries and anxiety. Of course, we should try our best to prepare things that are within our abilities in advance. But if this character goes beyond a certain point, one might do something by their own thoughts or plans although it is something that should be committed to God. This kind of person feels limited when they are faced with difficulties beyond their ability. 1 Peter 5:7 says, "Casting all your anxiety on Him, because He cares for you."
