Of course, yes. The Lord Jesus performed some public miracles after His resurrection. And here are a few of them:
1. The Resurrection itself.
By His resurrection, Jesus demonstrated that He triumphed over all His enemies by conquering death, an obvious superlative miracle (Matthew 28:11-15, 18; Colossians 2:15)
2. Appearing and disappearing at will.
After His resurrection, Jesus appeared to the disciples over a period of forty days and gave them many convincing proofs that He was alive (Acts 1: 3–4). Also He once disappeared miraculously (Luke 24:31).
3. Walking through closed doors.
Jesus appeared to the disciples who were meeting behind locked doors because they were afraid of the Jewish leaders (John 20:19). It was a great miracle for the frightened disciples to see the Lord standing before them live and bringing to them a message of hope and consolation.
4. Catching a huge number of fish.
When the disciples went fishing after the death of Jesus, they saw Him standing on the beach. But they couldn't recognize who He was until He caused them to catch 153 large fish in their net, yet the net was not torn (John 21:3-11).
5. The Ascension of Jesus.
After Jesus was resurrected and had appeared to the disciples with convincing evidence, He ascended into Heaven, taken up in the sky, which also was witnessed by them (Acts 1:1-11). This was actually the greatest public miracle in the Bible!
The apostle John testifies:
"This is the disciple who is bearing witness about these things, and who has written these things, and we know that his testimony is true. Now there are also many other things that Jesus did. Were every one of them to be written, I suppose that the world itself could not contain the books that would be written." (John 21:24-25)
