Saying a “sinner’s prayer” to be saved is not in the Bible. It is a man made command. Do not be deceived.
In critical thinking, you look at ALL the evidence and then you draw a conclusion. That’s exactly what Psalms 119:160 says. It’s the “SUM” of God’s word that is truth. Also, you need book, chapter, and verse or in other words “authority” from God’s own Word for your faith and practice. Matthew 7 shows us a picture of judgement where “RELIGIOUS” people are going to be turned away because what they did and practiced in the name of religion was WITHOUT LAW—or God’s authority. For, example the sinners’s prayer; no authority from God for that.
From the Bible we find many scriptures that tell us what to do to be saved. Like, Matthew 28:18-19, where Jesus is giving the Great Commission”. He says to go into all the world and make disciples , BAPTIZING them…”. Mark 16:16 Jesus also said that FAITH and baptism equals salvation. Romans 10:10 says that CONFESSION is unto salvation AND we have an example of someone’s salvation where they “confessed” their faith in Christ before baptism in Acts 8:37. In Acts 2:38 the apostle Peter told the Jews to REPENT and be baptized for the forgiveness of sins.
Remember Psalms 119:160? We are to add it all together to get the SUM of God’s word which is how we get the “TRUTH.” So we see from the scriptures we are to BELIEVE, REPENT, CONFESS, and be BAPTISED for the
forgiveness of sins.
Every Bible example of conversion substantiates this. The Jews in Acts 2:38, the Ethiopian eunuch in Acts 8, Saul of Tarsus in Acts 9, Lydia in Acts 16 and the jailer in Acts 16. Just to name a few.
Acts 17:11 teaches us to search the scriptures to see if what is taught is true. Men teach many different things but put your trust in God’s Word. See how people in the New Testament were saved. If God saved them that way—you can be sure He will save you if you do what they did.
