Note 31 at Joh 14:19: This is a reference to His crucifixion, only a few hours away. From that time on, the world (the unbelievers) would not be able to perceive Him, because they could not see Him (Joh 14:17). However, His followers would be able to fellowship with Him through the ministry of the Holy Spirit even though they could not physically see Him.

Note 32 at Joh 14:19: This was a promise from Jesus that just as His body would be resurrected, so ours will be also.
