Final answer:
The question refers to the biblical concept of blasphemy against the Holy Spirit, which Jesus mentions as the unforgivable sin, traditionally understood within Christian theology.
Step-by-step explanation:
The statement 'Whose words will not be forgiven him from this age or in the age to come?' refers to a biblical concept found in the context of the teachings of Jesus.
It specifically addresses the unforgivable sin, which is often interpreted as blasphemy against the Holy Spirit.
This concept is mentioned in the Gospels of the New Testament, where Jesus is speaking to the Pharisees after they claimed that His miracles were done through the power of Beelzebul (the prince of demons), not through the Holy Spirit.
