Jesus and his heavenly Father
Jesus tells James and John that granting places at his left and right is not for him to grant. Does he mean it is not his to grant in his humanity or it is not the Son's to grant but the Father's decision? If the latter is true, then what about the authority as judge that Jesus holds?
Jesus’ words tell us that the Father, who planned the world’s salvation and sent his Son into the world to fulfill that mission (John 3:16), also determined places of honor in his heavenly kingdom.
Jesus also explained that his heavenly Father has entrusted him with the judgement of all people on the Last Day (John 5:22, 27; Acts 10:42; 17:31). That is appropriate since it is people’s attitude toward Jesus and his gospel that determines where people will spend eternity.
