As in Ezekiel's experience, the scroll tasted sweet in the mouth (Ezekiel 3:1–3; see Jeremiah 15:16; see also Psalms 19:10; 119:103). The future experiences for God's people would be sweet, including the victory of God's plan and the vindication of his people. John's bitter stomach is similar to the effects of Ezekiel's tough message for Israel (Ezekiel 3:8–9). The process of fulfilling God's plan involves hardship.
