What does Mark 16:14 mean?
Readers of Mark would be excused for never questioning that this verse is original to the text. Though this verse was a later addition to Mark's Gospel, the content seems to fit with earlier parts of Mark. As recorded by Mark, Jesus has spent three years fighting the hard hearts of Pharisees, scribes, Herodians, and chief priests, but also, and perhaps most frustratingly, His disciples. The Twelve liked the perks of following an avant-garde rabbi (Mark 2:18, 23; 4:10, 34; 6:7–13; 7:1–2) and had no problem letting their insider position go to their heads (Mark 9:33–37, 38–41; 10:13–16, 35–45). But time and again they proved that Jesus' message didn't get into their hearts (Mark 8:14–21, 31–33).However, this verse is not original to Mark. It is a summary of Luke 24:36–44 and John 20:19–29. Most likely, this was added in the form of a footnote, or addendum, which was mistakenly absorbed into the text itself by a later scribe.
Jesus appears to the disciples and other followers who are so startled and frightened at His appearance they think He is a spirit. He shows them the nail holes in His hands and feet and invites them to touch Him to see that He has flesh and bones. "They still disbelieved for joy and were marveling" (Luke 24:41; John 20:20). Jesus requested food and they gave Him some broiled fish to eat. It seems this is when the disciples began to understand. Jesus then "opened their minds to understand the Scriptures" about Messiah (Luke 24:44–49).
All of us have experienced hardships and difficulties that we know God has allowed but hasn't explained. Once we are through, we see the reason, whether for blessings or to prepare us for a greater work. The disciples have undergone the same thing. On the third time Jesus told the disciples of His coming death, Luke explains, "But they understood none of these things. This saying was hidden from them, and they did not grasp what was said" (Luke 18:34). Now, as Jesus explains what the Jewish Scriptures really say about the Messiah, "he open[s] their minds to understand the Scriptures" (Luke 24:45).
Clearly the disciples could not understand what was hidden from them, but they, like we, should have been faithful to what they were taught. We need to adopt Paul's charge to Timothy, "continue in what you have learned and have firmly believed, knowing from whom you learned it" (2 Timothy 3:14). If we accept and act on what little we understand of God's plan, He will reveal more to us (Matthew 25:21).
