Bible Notes Online - John 21 - ESV
Commentary

v1-3: John sets the scene; the Sea of Tiberias (Galilee), 7 disciples fishing, a fruitless night's work.

v4-6: The vision and the command; and blessing through obedience, 1 Kings 17.15. Any work done in Jesus' strength at His command is fruitful, 1 Cor 15.58.

The result here was a multitude of fish, prefiguring what would happen at Pentecost.

v7: It was John who first recognised the Lord; here is spiritual perception, for He had often been close to Jesus.

Simon Peter, always quick to respond, dived into the water; in 20.3-7, he had rushed first into the empty tomb. We see also Peter’s boldness; later this matures, as seen in his sermon on the day of Pentecost (Acts 2), and his words before the Sanhedrin (Acts 4).

John and Peter were different characters, but they clearly loved Jesus; their expression of that love was different.

v8: The disciples were in a 'little boat,' dragging a net full of fish.

v9: Practical kindness and caring; Jesus already had bread and fish for the disciples.

v10: Jesus asked for some of the fish they had just caught; He did not despise their work, giving value and dignity to what they had done.

v11: 153 fish, not one was lost (17.12; 2 Tim 2.19), and the net was not broken. Will not the Lord of the Church ensure that our "net" is always large enough and strong enough. 

Sometimes the Lord calls us to carry a heavy load, to have more than the usual responsibilities. Sometimes life seems to conspire such that several major challenges arrive at the same time.

At such times we find that our nets do not break. God gives us ample strength for those days.

v12-14: Jesus served the breakfast; here is quality of leadership, setting an example.

The disciples were speechless with joy.

v15-16: Jesus took Peter aside, to deal with him, bringing forgiveness and acceptance and restoration. Jesus challenged Peter over his love for Him. See Mark 14.29,71.

v17: Peter was grieved at the three-fold question. This matched Peter's three-fold denial of the Lord. Sin must be dealt with properly; exposed, confessed, and forgiven; Prov 28.13; 1 John 1.9. We may confess too easily, without real meaning. Forgiveness promotes real love, Luke 7.47.

The special commission for Peter; feed my lambs, tend my sheep, feed my sheep. Peter had to teach both young Christians (lambs) and more mature Christians (sheep). A herdsman feeds, a shepherd tends; Peter was to be both, 1 Pet 5.1-4.

Christ's work demands a Christ-like character. If we are to feed His lambs, and His sheep, serving His church, then our character must be like Him.

v18-19: The prophesy that Peter would glorify God in His death, Ps 116.15. One mark of the Christian church has always been its martyrs; and always will be, Rev 12.11. We can glorify God throughout our lives, right to our final breath, and beyond; we can thus leave a glorious testimony to our Lord and Master. ‘See what a good Master they serve, and how they love Him.’

We note that Peter was dealt with individually, as were Mary and Thomas in chapter 20; the Lord knows His sheep.

Do you love me? A question of devotion and adoration; not of doctrine and understanding, not of practice and commitment; for all these must flow from a loving heart, see 14.21;23; 2 Cor 5.14; 1 John 3.16-18.

v20-21: Peter pointed the finger towards John; but our first responsibility is our own lives, Rom 14.12; 2 Cor 5.10. We may fall into an attitude of criticism or interference; it is better to endorse or commend.

v22-23: The problem of misunderstanding, which spread from the seven disciples hr to "the brothers."

v24: See 19.35; eye-witness testimony; we have confidence that these things really happened.

v25: The events recorded are selected; for Jesus did so much in a short period of ministry.
