John 6:28-64. The people asked Jesus, "What must we do to do the works God requires?" Jesus replied, "The work of God is to believe in the one he has sent." The people then asked Jesus what miraculous sign he would perform such that seeing it would prove he was the one God has sent who should be believed. They cited the miracle by Moses of manna from heaven as an example, to which Jesus stated that God gives the true bread from heaven, which is he who comes down from heaven and gives life to the world. The people asked Jesus to give them this bread, and Jesus declared that he is the bread of life, and whoever believes in him will never go hungry or be thirsty, but he accused them of disbelief even a though they have seen him.
Then Jesus said that all the Father gives him and whoever comes to him he will never drive away, because he has come down from heaven to do the will of Him who sent him, and the Father's will is that everyone who looks to the Son and believes in him shall have eternal life, and Jesus will resurrect them at the last day. The people grumbled upon hearing him claim to be the bread that came down from heaven, saying, "Is this not Jesus the son of Joseph and his mother whom we know?
Jesus reproved their grumbling and explained that he is the bread of life who dies for the life of the world, so whoever partakes of his body will live forever. Many of his disciples found this teaching too hard to accept, but Jesus said "The words I have spoken to you are spirit and life, yet some of you do not believe."
The question asked by the people is equivalent to what the Philippian jailer asked Paul and Silas in Acts 16:30: "What must I do to be saved?" Their answer was, “Believe in the Lord Jesus.” (Acts 16:31, cf. 2Cor. 4:5 & Col. 2:6), which is equivalent to the answer of Jesus in John 6:29. This nutshell statement of God's requirement for salvation implies the following five points:
- There is a/one all-loving and just Lord or Creator God (Deut. 6:4, John 3:16, 2Thes. 1:6), who loves sinful humanity (Rom. 5:6-8, John 3:16) and who is both able (2Tim. 1:12) and willing (1Tim. 2:3-4, Ezek. 33:11) to provide all morally accountable human beings salvation or heaven—a wonderful life full of love, joy and peace forever.
- Human beings are selfish or sinful (Rom. 3:23, 2Tim. 3:2-4, Col. 3:5), miserable (Gal. 5:19-21), and hopeless (Eph. 2:12) or hell-bound at the judgment (Matt. 23:33 & 25:46) when they reject God’s salvation (John 3:18, Rom. 2:5-11).
- Jesus is God’s Messiah/Christ and incarnate Son, the way that God has chosen (John 3:16, Acts 16:30-31, Phil. 2:9-11) of providing salvation by means of his atoning death on the cross for the payment of the penalty for the sins of humanity (Rom. 3:22-25 & 5:9-11), followed by his resurrection to reign in heaven (1Cor. 15:14-28).
- Thus, every person who hears the NT Gospel needs to repent and accept God’s grace or justification in Jesus as Christ/Messiah the Lord or Supreme Commander (Luke 2:11, John 14:6, Acts 16:31), at which moment God’s loving Holy Spirit of Christ indwells/baptizes the believer into the church (Rev. 3:20, Rom. 5:5, 1Cor. 12:13).
- Loving Christ Jesus as Lord (Luke 2:11), God the Son (Matt. 16:16) or God in the human dimension (Col. 2:9) means reflecting divine love as empowered by the Holy Spirit, thereby obeying His command to love one another (Matt. 7:21, 22:37-40, John 13:35, Rom. 13:9)—forever (Matt. 10:22, Psa. 113:2), which will eventually achieve spiritual maturity on earth and heaven after Christ returns at God’s resurrection (John 14:6, 17&26, Rom. 8:6-17, Gal. 6:7-9, Eph. 1:13-14, Phil. 3:12-16, Heb. 10:36, 12:1, Jam. 1:2-4).
Regarding the miracle of manna, Jesus viewed it as signifying the word of God, as in Matt. 4:4. Reference to life for the world and believing in him reiterated John 3:16 and, and the metaphor of bread is analogous to that of light in John 1:4-14 and of water in John 4:10-14, hence the mention of not going thirsty in John 6:35. Regarding being taught and drawn by God, this truth foreshadows what will be stated most starkly in John 8:42-47. Jesus instituted the symbolic partaking of his body to memorialize his death in the Last Supper (Matt. 26:17-29, cf. 1Cor. 11:23-26).
