Matthew 19:27
Then Peter said in reply: see, we have left everything and followed you. What then will we have? Peter's we-have-left-everything is the contrast to the rich young man's he went away keeping everything. Peter's question — what will we have — is the disciples' legitimate inquiry about the reward that the sacrifice of following Jesus produces. The question is not purely mercenary; it is the honest recognition that Jesus has promised treasure (verse 21) and the disciples have paid the cost.
