(35) Jesus said to them, "I am the bread of life; whoever comes to me shall not hunger, and whoever believes in me shall never thirst. (36) But I said to you that you have seen me and yet do not believe. (37) All that the Father gives me will come to me, and whoever comes to me I will never cast out. (38) For I have come down from heaven, not to do my own will but the will of him who sent me. (39) And this is the will of him who sent me, that I should lose nothing of all that he has given me, but raise it up on the last day."
– John 6:35-39

Salvation by Christ's work is a gift of grace received through faith. This salvation is total (Romans 8:30) and we see its totality in John 6. In Christ, we are:

1. Satisfied (vv.35-36)
No more hunger. No more thirst. When we are full of Christ, we are truly full. He is the end of our fruitless searching for satisfaction, our appetites for idols.

2. Secured (v.37,39)
Never cast out, never lost. His securing hand (John 10:28), like his securing love (Romans 8:35-39), is omnipotent. If a Christian is united to Christ, he is as secure as Christ is.

3. Supernaturalized (v.39)
Heaven has come down to invade earth in Christ, and by God's grace, heaven invades the very souls of his children (John 14:17, Romans 8:9) and sets up shop (Ephesians 2:22). Indwelt by the Spirit who seals (Ephesians 1:13), guarantees (2 Corinthians 1:22), instructs (John 16:13), and empowers (Acts 1:8, Ephesians 3:16), we are new creations (2 Corinthians 5:17), growing in grace (2 Peter 3:18) and bearing capital-S Spiritual fruit (Galatians 5:22-23), consecrated for the day we will receive our inheritance—- glorified bodies (1 Corinthians 15:42-49).

By and in Christ, we are utterly saved.

Consequently, he is able to save to the uttermost those who draw near to God… —Hebrews 7:25
