Heavenly feasting

There are many references to a feast in heaven. Is this symbolic or will there actually be food?

The Bible definitely uses the imagery of feasting as part of the description of our eternal joys in the presence of God in heaven (Isaiah 25:6; Matthew 8:11; 22:1-4; and, Revelation 19:9).

Then there are passages—in literal contexts—that speak of eating and drinking in heaven (Matthew 26:29; Luke 22:29-30). What that might consist of, we will have to wait and see. (But it will be worth the wait!)

We do know that there will not be problems like hunger or thirst in heaven (Revelation 7:16). Those are problems caused by sin. Life with God in heaven will be an eternal existence in which Christians are free from sin and all its consequences.
