You revealed to mere children the mysteries of the Kingdom

" At that time Jesus said in reply, “I give praise to you, Father, Lord of heaven and earth, for although you have hidden these things from the wise and the learned you have revealed them to the childlike."  (Matthew 11: 25)

What has our dear Abba Father hidden from the wise of this world and revealed to mere children?  Our Father has given the gift of faith to the childlike.  He revealed to them the mysteries hidden in the seven Sacraments:  Baptism, Eucharist, Confirmation, Penance, Matrimony, Holy Orders and Anointing of the Sick.  The childlike accept that Jesus Christ is in these Sacraments and work through these Sacraments.

The childlike are distinguished from the learned from having the gift of faith.  Faith gives us access to the mysteries of the Kingdom.
