Then glancing round him in anger and vexation at their obstinacy he told the man, "Stretch out your hand." He stretched it out and his hand was quite restored.

Afterwards he appeared at table to the eleven themselves and reproached them for their unbelief and dulness of mind, because they had not believed those who saw him risen from the dead. [But they excused themselves, saying, "This age of lawlessness and unbelief lies under the sway of Satan, who will not allow what lies under the unclean spirits to understand the truth and power of God; therefore," they said to Christ, "reveal your righteousness now." Christ answered them, "The term of years for Satan's power has now expired, but other terrors are at hand. I was delivered to death on behalf of sinners, that they might return to the truth and sin no more, that they might inherit that glory of righteousness which is spiritual and imperishable in heaven."]
