Here are links for Greek commentary on all four Gospel
Summary: The big story in John is that Mary needs to hear Jesus call her by name. At that point, she recognizes Jesus. In our grief and sorrow, we can over look Jesus and his resurrection until we hear Jesus call us by name, which he does in our Baptisms. But if you already preached THE John sermon, here are some other ideas.
μνημειον ("tomb", 20:1) This word comes from the Greek for memory (like English "mneumonic" is something that helps you remember). The complaint almost reads, "They have taken Jesus out of my memory!" There is something to play with here, about memory and loved ones. Jesus isn't just a memory; your loved ones aren't just a memory. Jesus is alive!
οιδαμεν ("know" from ειδω, 20:2, 9 and 13). This word comes from ειδω, which means to see. In the perfect sense (I have seen), it means I know. The point here is that John is subtly combining the ideas of knowing and seeing; and there is a lot more of seeing going on than first anticipated. Also, this verb is in the plural, suggesting that Mary is not alone (hence synchronizing with the synoptics).
εθηκαν ("place", from τιθημι, 20:2) This verb is all over John's Gospel, most importantly in chapter 10, when Jesus discusses himself as the Good Shepherd who will lay down his life. No one lays down Jesus; only Jesus himself does this. Jesus also praises one who lays down his life (John 15:13) and asks if the disciples will lay down their life (13:37)
οθονια ("fine linen", 20:5, 6 and 7) I never realized it was high quality linen they put around Jesus! Interestingly, this can refer in ancient Greek to a sail. Okay. Back to reality. The point is that Jesus had the finest stuff that he even took time to roll up!
αυτους ("themselves", 20:10) This word here is translated as "home." But the Greek doesn't say home. It literally reads, "They went back to themselves." I think one can picture them simply going off to ponder what had happened rather than simply going back to life as it were
ο κηπουρος ("gardener", 20:15) The big deal here is that Jesus is THE gardener. Where is Jesus after the resurrection. GARDENING! Also worth noting is that like in the OT, when angels speak the Word of the Lord, the Lord shows up.
20:9 Infinitive phrases: subject takes accusative
Just a quick reminder that in infinitive phrases, the subject is found in the accusative case. Hence "it was necessary for Jesus to rise from the dead" and not "it was necessary for him to raise Jesus from the dead."
