That is when one read scripture out of context and shortsightedly testify one's own or denomination version.The bible does not teach that Christ died for everybody in the whole world but for His sheep:
John 1:
29. The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of GOD, which taketh away the sin of the world.
Indeed Jesus died for everybody, it is just that who choose to believe and who choose not to believe.
John 16:
8. And when He come, He will reprove the world of sin, and of righteousness, and of judgement:
9. Of sin, because they believe not on Me;
They are no longer accounted for sin based on violating the moral law of GOD.
But rather of sin, they believe not on Jesus Christ who have already taken those sin away.
Ephesians 2:
19. Now therefore ye are no more strangers and foreigners, but fellowcitizens with the saints, and of the household of GOD;
20. And are built upon the foundation of the apostles and prophets, Jesus Christ Himself being the chief corner stone;
Shalom in the name of Jesus Christ
