Juan 4:36

The reaper in view was Jesus, and potentially His disciples could become reapers. The wages that reapers receive are the reward for their labor. For Jesus this was the exaltation that the Father gave Him and will give Him for carrying out His will faithfully. For the disciples it is rewards that they and we can receive at the judgment seat of Christ for faithful service. Some of this reward comes immediately in the form of satisfaction and perhaps other blessings. The fruit is probably a reference to the people as grain that will obtain eternal life. The one who sows is anyone who proclaims the gospel, but ultimately Jesus (cf. Matthew 13:37).
