Revelation 10
v1-7: There are things that God wants us to know and there are things that He doesn’t. Those things that He doesn’t want us to know about include details about His plans for the future (what the seven thunders said). However, we should not let this worry us because the important things we need to know God has told us and He can be trusted with what we don’t know.
v8-11: We are to take God’s words to heart, believing them, and being transformed and shaped by them. This will be a bittersweet experience, with both pleasant and painful parts to it. There is a real sweetness in the message of the gospel because it saves sinners, but it is also sour because it brings “such grievous persecutions” to “the people of God” from a world that hates Christ, as John knew. He was imprisoned in Patmos because of the Word of God and the testimony of Jesus. Yet “God’s messengers must not keep back any part of the will of God.” We eat it, then we speak it.
