Final answer:
Jesus resisting the devil's temptations was essential because yielding would contradict His sinless nature, undermining His purpose as the Savior in the Judeo-Christian tradition. Jesus maintained His righteousness, which was necessary for His role in human redemption.
Step-by-step explanation:
It would have been a sin for Jesus to give into the devil's temptations because in the Judeo-Christian tradition, Jesus is recognized as both fully divine and fully human, yet without sin. To succumb to sin would contradict His nature and mission, which was to lead by example and overcome sin, ultimately offering redemption to humanity. According to the narrative in Matthew 4:1-11, Jesus enduring and resisting temptations was a testament to His righteousness and His qualification to be the Savior.
In Christianity, sin is considered a moral evil, and Jesus's resistance to temptation was crucial in maintaining His sinless nature and ensuring His sacrifice would be sufficient for the salvation of mankind. James 1:13 reinforces the belief that God cannot be tempted by evil, and by extension, His incarnate form, Jesus, would also be above yielding to evil temptation.
The LibreTexts' account of Adam and Eve refers to human failings and their susceptibility to the devil's temptations. As the New Testament presents Jesus as the second Adam who succeeds where the first Adam failed, giving in to temptation would have nullified the redemption arc and the purpose of Jesus's sacrificial death, according to Christian doctrine.
