When people say “It’s not about what we do, but what Christ did”, this can come across to many as we have nothing at all to do to be saved. To get around this, it is argued that if it’s all about what He did then all would be saved since He died for all (John 3:16)
However, let’s see if that phrase “It’s not about what we do, but what Christ did” is a biblical one.
Titus 3:3 For we ourselves also were sometimes foolish, disobedient, deceived, serving divers lusts and pleasures, living in malice and envy, hateful, and hating one another.
4 But after that the kindness and love of God our Saviour toward man appeared,
5 Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost;
6 Which he shed on us abundantly through Jesus Christ our Saviour;
7 That being justified by his grace, we should be made heirs according to the hope of eternal life.
Ephesians 2:8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: 9 Not of works, lest any man should boast.
In those passages, we can see that we did nothing on our own without God to be saved. We did nothing in our own merit/righteousness or works to have Jesus come and save us by His grace.
So, the part “It’s not about what we do” with regard to developing a way of being saved is correct.
However, does this mean there is nothing we must do in order to be saved? Let’s see
Matthew 7:21 - " he who does the will of my father in heaven"
Matthew 7:24-27 - "whoever hears these sayings of mine and does them"
Mark 10:17 - "Good teacher, what shall I do that I may inherit eternal life?"
Acts 2:37-38 - "what shall we do?"
Acts 9:6 - "Lord, what do you want me to do?"
Acts 16:30 - "Sirs, what must I do to be saved?"
As we can see, there are many cases of people asking what they must do…So, the idea behind “It’s not about what we do” must be referring to we did nothing to save ourselves by ourselves, nor did we circumvent a way apart from the Godhead to be saved.
From that aspect, “it’s not what we do” because we didn’t invent the way of Jesus to save us. He saved us of His own doing in what He did by going to the cross. We did not do that for us. And out of love we obeyed Him.
The part that says “it’s about what Christ did” is referring to Him giving His life for us.
So technically, that phrase is a biblical view, but some people in denominations use it to say they don’t have to do one thing to be saved or live for Christ since it’s not about us. And they are right concerning the latter, because it’s not about us. And it never has been. It’s about Christ.
It is not our works that makes us righteousness (Titus 3:5). It is faith in Christ that does by the power of the gospel (Rom. 3:22, Phil. 3:9, Rom. 1:16).
The works of Christ that save us is His death, burial, resurrection, and what He has commanded us to do—which those are God given commandments to be saved by His grace.
The term “works” is sometimes the equivalent of “obedience.” Elsewhere Jesus promised victory to those who “keep my works,” i.e., the works (commands) prescribed by him (Rev. 2:26)
His grace instructs us (Titus 2:11-12).
Gal. 3:24 Therefore the law was our tutor to bring us to Christ, that we might be justified by faith.
Romans 5:1-2 Therefore, having been justified by faith, we have peace with God through our Lord Jesus Christ, through whom we also have access by faith into this grace…
Gal. 3:24 says justified by faith
How does get into this grace in Romans 5:2? They have to be justified by faith. But how is one be justified by faith? One must be baptized into Christ (Gal. 3:27), and that is where we have access by faith into this grace (Rom. 5:2).
