2:8 For by grace you are saved19 through faith,20 and this is not of yourselves, it is the gift of God; 2:9 it is not of works, so that no one can boast.21 - Ephesians 2:8-9 NET
Salvation is by grace through faith, other blessings might depend on obedience but salvation is a free gift.
22:17 And the Spirit and the bride say, “Come!” And let the one who hears say: “Come!” And let the one who is thirsty come; let the one who wants it take the water of life free of charge. - Revelation 22:17 NET
Forgiveness comes only with the shedding of blood, not through works.
9:22 Indeed according to the law almost everything was purified with blood, and without the shedding of blood there is no forgiveness. - Hebrews 9:22 NET
It is through Christ's resurrection that we are born again not be works of merrit.
1:3 Blessed be the God and Father of our Lord Jesus Christ! By his great mercy he gave us new birth into a living hope through the resurrection of Jesus Christ from the dead, 1:4 that is,8 into9 an inheritance imperishable, undefiled, and unfading. It is reserved in heaven for you, - 1 Peter 1:3 NET
When Paul and Silas' guard asked what he must do to be saved, their reply did not mention works, only belief in Christ.
16:30 Then he brought them outside107 and asked, “Sirs, what must108 I do to be saved?” 16:31 They replied,109 “Believe110 in the Lord Jesus111 and you will be saved, you and your household.” - Acts 16:30-31 NET
Again, salvation is through faith in Christ not works of righteousness.
10:5 For Moses writes about the righteousness that is by the law: “The one who does these things will live by them.”5 10:6 But the righteousness that is by faith says: “Do not say in your heart,6 ‘Who will ascend into heaven?’”7 (that is, to bring Christ down) 10:7 or “Who will descend into the abyss?”8 (that is, to bring Christ up from the dead). 10:8 But what does it say? “The word is near you, in your mouth and in your heart”9 (that is, the word of faith that we preach), 10:9 because if you confess with your mouth that Jesus is Lord10 and believe in your heart that God raised him from the dead, you will be saved. 10:10 For with the heart one believes and thus has righteousness11 and with the mouth one confesses and thus has salvation.12 10:11 For the scripture says, “Everyone who believes in him will not be put to shame.”13 - Romans 10:5-11 NET
Yet again, the Bible says that salvation is by grace and forgiveness is through the blood of Christ.
1:7 In him18 we have redemption through his blood, the forgiveness of our trespasses, according to the riches of his grace - Ephesians 1:7 NET
And finally, this is what Paul had to say about the gospel:
15:1 Now I want to make clear for you,1 brothers and sisters,2 the gospel that I preached to you, that you received and on which you stand, 15:2 and by which you are being saved, if you hold firmly to the message I preached to you—unless you believed in vain. 15:3 For I passed on to you as of first importance3 what I also received—that Christ died for our sins according to the scriptures, 15:4 and that he was buried, and that he was raised4 on the third day according to the scriptures, 15:5 and that he appeared to Cephas, then to the twelve. 15:6 Then he appeared to more than five hundred brothers and sisters5 at one time, most of whom are still living,6 though some have fallen asleep.7 15:7 Then he appeared to James, then to all the apostles. 15:8 Last of all, as though to one born at the wrong time,8 he appeared to me also. 15:9 For I am the least of the apostles, unworthy to be called an apostle, because I persecuted the church of God. 15:10 But by the grace of God I am what I am, and his grace to me has not been in vain. In fact, I worked harder than all of them—yet not I, but the grace of God with me. 15:11 Whether then it was I or they, this is the way we preach and this is the way you believed. - 1 Corinthians 15:1-11 NET
Notice that the crucial core of the Christian faith is that Christ paid the price for our sins and that he arose from the dead according to the scriptures, works such as baptism are not mentioned.
