'Manifestation' in the Bible

For the message of the cross is foolishness [absurd and illogical] to those who are perishing and spiritually dead [because they reject it], but to us who are being saved [by God’s grace] it is [the manifestation of] the power of God.

But to each one is given the manifestation of the Spirit [the spiritual illumination and the enabling of the Holy Spirit] for the common good.
