What does Luke 24:39 mean?
In the Bible, faith and fear do not belong together (1 John 4:18). If Jesus' disciples really believe He is the Son of God, the Messiah, they should not be afraid of storms (Luke 8:22–25), persecution by the religious leaders (Mark 14:50), or even His death on the cross. If He is the one who will fulfill the prophecies of the Old Testament, He will do it, even if He must rise from the dead.Sometimes, Jesus chastises His disciples' unbelief. Sometimes, He knows what they're witnessing is too much. When they saw Him walking on the stormy Sea of Galilee, they were terrified, thinking He was a ghost. He told them, "Take heart; it is I. Do not be afraid" (Mark 6:49–50).
Now, despite the eye-witness testimony of multiple people and His appearance in a locked room in a new, healed body, some of His disciples are so overcome they still can't believe it's Him. Or, if it's Him, that it's only His spirit (Luke 24:36–38).
Jesus shows compassion on their limitations and gives them what they need: to see the wounds on His hands and feet where the nails went through. To touch Him to affirm this is really a physical body. To watch Him eat fish, which no spirit could do (Luke 24:40–43).
Some teachers think that Christianity requires blind faith. That was never the case. God gives us promises to believe in. The more we believe, the more He gives us. Along the way, He gives proof that His promises are true. It's when we harden our hearts against the truth that we get in trouble (Luke 8:18; Romans 1:18–22).
Jesus' body resembles the glorified bodies His followers will have for eternity (1 John 3:2). He has a physical body, so will we. His wounds are healed, except for those that mark His sacrifice; ours will be, too. Also, our bodies will be spiritual in that they will be animated by choices guided by the Holy Spirit, not our sinful desires (1 Corinthians 15:35–44).
