Revelation 10:8-11 highlights an encounter between John and an angel. The angel instructed John to eat a scroll and assured him that it would be sweet and pleasant, but in his stomach, it would turn bitter and sour.
This passage can present itself as something challenging to comprehend and analyze. We can say that this mysterious scroll is the Word of God. As believers, we experience this bitter-sweetness quite often. The message and goal of the Gospels are sweet and pleasant. However, due to us still being humans, the sacrifices we are obligated to make to live a genuine Christian lifestyle can be challenging; bitter.
After John eats the scroll and experiences everything the Angel said. The Angel then demanded that John go back and prophesy to ALL PEOPLE, of ALL NATIONS, of ALL LANGUAGES, and ALL GOVERNMENTS.
This can apply to us because once we become born again into the Kingdom of God we must accept the sweet and the bitter and do what we as disciples are supposed to do which is to proclaim the Lordship of Jesus Christ to everyone, because this is what we have been called too.
