What does the Bible say about Christ dying for everyone?

Scripture indicates that Christ's sacrificial death did not encompass every individual, but rather was for those who are deemed 'God's elect.' 2 Corinthians 5:14-15 highlights that 'if one died for all, then we're all dead,' inferring that Christ's death pertains to those who would ultimately live for Him. It becomes crucial to understand that while many proclaim Christ died for all, the biblical narrative consistently reveals a distinction between the world at large and the specific people written in the Book of Life. Revelation 20 speaks to the judgment where only those found in the Book of Life will be saved. Thus, the assertion that Christ died for everybody negates the specificity and power of His redemptive work, which guarantees salvation for His chosen ones.
