What does the future hold?
What will come will reveal what has been held back.
John was going to write down what he heard but was commanded not to. Less is more. Suspense is created. There are things about the end of the world we simply do not know and the reason is this verse, v4.
What will come is a mystery.
Not a secret. But an open secret. God’s plan that was announced to his servants, v7. This is a word meaning to evangelise, to preach. The first 6 judgements are not the last word. God has that. But for that to happen involves the mystery. That means God’s people are involved sharing the good news.
What will come will cost.
John eats the scroll like Ezekiel did but for John though the scroll tastes sweet it then leaves a sourness in his stomach, v10. John and his churches have the privilege of sharing the good news and seeing its benefits. Yet just like John is on Patmos because of doing so so God’s people will suffer for the gospel.
That is what will come.
