Nah, you’re angry and self righteous. You get hostile when you can’t control people who disagree with you. You also think your salvation depends on your actions. That’s works salvation which is heresy.
God’s grace is a free gift given to people who place their faith in Jesus Christ. If you actually think the simplicity of John 3:16-18 is a false scriptural reference then you are to be pitied.
I find it interesting when people declare others self righteous that insist on being obedient to what the Word actually says.
You point out John 3:16-18. I suggest you begin at John 3:1 to see what believing in Jesus entails. It is important to realize that Jesus is the Word of God manifest in the flesh. This means to reject the truths expressed in the Word is in fact a rejection of Jesus. This truth is seen from Jesus' words recorded in John 12:48:
"
He that rejecteth me, and
receiveth not my words, hath one that judgeth him:
the word that I have spoken, the same shall judge him in the last day."
Also relevant is the fact that Peter's entire message was actually prompted by Jesus via the Holy Ghost that Peter just received on the Day of Pentecost:
"The former treatise have I made, O Theophilus, of all that Jesus began both to do and teach,
Until the day in which he was taken up,
after that HE (Jesus) THROUGH the Holy Ghost had given commandments unto the apostles whom he had chosen:" (Acts 1:1-2)
