God is all-knowing and all-wise.

God's knowledge is exhaustive and perfect; whereas, our knowledge is partial and imperfect.

God is also all-wise.

We see God's wisdom in creation, God's plan of redemption, in the Church, and most of all in Jesus.

God's knowledge and wisdom is a call to humility. It's a call to Scripture and to prayer.  It's a call to seek the mind and will of God.
