You are simply insisting against the words of the Master Teacher. If that is not being dumb and anti-Christ, then how would you call it? We are born in Christ, hence born saved.
When people sin, the Holy Spirit is not taken away. The HS continues to convict them of their wrong-doings. You also sin, don't you? Has the HS been taken away from you? No. You continue to be led by the HS despite your sins. But the fact that the HS continue to lead you, does not leave you off the hook. If you continue to be overcome of evil instead of overcoming it with good, then when you die NOT an overcomer, your name will Christ blot out from the book of life (Rev 3:5), that's when you are lost forever (Rev 20:15, 21:27).
Again, our Lord & Savior through the parable of the lost sheep, lost coin and lost son made clear that people start out NOT lost. And to be NOT lost is to be in Christ. He said He came to seek and save that which was lost. He did not fail in His mission. He reported to the Father that He has finished the work He was assigned to do (John 17:4). He already found us, as He explained in the parable of the lost. The sheep, coin and son were all found.
