Goodbyes are difficult and often a source of sorrow. In John 16:16-22 the disciples were wrestling with a goodbye of their own as they pondered Jesus's announcement that they will not see him for a little while. Jesus encourages them by giving them a promise. He promises to turn their sorrow into joy (vs. 20). This is the power of the resurrection. The eternal joys offered by God and promised in Christ are rooted in the resurrection of Jesus for all who are united to him by faith.
