The answer is indicated by the fact that, after mention of the definite number 144,000 (Revelation 7:4), Revelation 7:9 refers to “a great crowd, which no man was able to number.” If the number 144,000 were not literal it would lack meaning as a contrast to the “great crowd.” Viewing the number as literal agrees with Jesus’ statement at Matthew 22:14 regarding the Kingdom of the heavens: “There are many invited, but few chosen.”
