Contradiction with Luke 19:10
This verse states that the Son of Man has come to seek and to save that which was lost, which can be seen as more inclusive than the specific saving from sins mentioned in Matthew 1:21.
Luke 19:10: For the Son of man is come to seek and to save that which was lost.
Contradiction with James 2:24
This verse says a person is justified by works and not by faith only, which differs from Matthew 1:21's idea of salvation through Jesus implying faith in Him.
James 2:24: Ye see then how that by works a man is justified, and not by faith only.
Paradox #1
Some people see a potential contradiction between the idea that Jesus came to save his people from their sins and the existence of judgment or punishment for sins elsewhere in the Bible. They might wonder if sins can be truly forgiven, should there still be consequences or judgment. However, theological explanations often reconcile this by discussing concepts like repentance, faith, and the difference between spiritual and earthly consequences.
Paradox #2
The contradiction or inconsistency could be related to the interpretation of the name and role of Jesus. Some argue over the understanding of Jesus' mission and identity as presented in different texts or traditions, especially when comparing the New Testament writings to Old Testament prophecies or to interpretations in different branches of Christianity and Judaism.
