Your leaving a great deal of scriptures out that also discuss salvation Even the demons believe Jesus is Lord and in his resurrection . Real salvific faith involves more than just intellectual assent.M1Buckeye said:
Many falsely believe that God people day and night forever and ever.
Philippians 2:10-11 so that at the name of Jesus every knee should bow, in heaven and on earth and under the earth, 11 and every tongue confess that Jesus Christ is Lord, to the glory of God the Father.
Romans 10:9 because, if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved.
Matthew 1);22,32
1 Corinthians 6:9-10
The 'one and done' theology is absolutely not supported by scripture.
