Have you ever tried cooking a frog? I haven't, but it sounds kinda interesting. You see, in order to cook a frog you have to do it when it's alive (I don't know why, you just do). But the thing is is that frogs jump. I know what you're thinking, "Well DUH Jayla, frogs are supposed to jump!" well, if frogs jump then what do you think will happen when they touch the boiling hot water you're about to cook them in? They jump out of it right? But if you put it in a pot of cool water and slowly heat it up then they won't notice.
Now for the explanation for the weird analogy. You see, Satan knows how to "cook our frogs" so to speak. He knows that if he just slowly tempts us into "minor" sins, then after a while we won't notice how far away we've gotten from God. Like, did you know that when television was first popular, even if two people were married on the show they still had separate beds on the show because they didn't want any impurities? Now it seems like if a show doesn't have two people sleeping together that aren't married at some point or another, it's just reruns of an old show. This is how you boil a frog. We need to be very careful so we don't let this happen to ourselves, because if we're not careful we'll end up getting cooked.
