Occasions of sin are not temptations. An occasion of sin is a noun – that is, a person place or thing, or idea – in which or by which we might be led to sin, when we might be tempted. Good things are attractive, therefore good things will be more likely to present us with temptation and are more dangerous to us in terms of temptation, not always in themselves but potentially. For example, a person is much more likely to overeat on cheeseburgers than on kale. So good things, certainly more than bad, can be occasions of sin for us. But that does not thereby make the good thing bad.
