After Jesus sends out the 72 and they return successfully, Jesus was full of joy through the Holy Spirit and prayed "I praise you Father, Lord of heaven and earth, because you have hidden these things from the wise and learned, and revealed them to little children, yes Father for this was your good pleasure." Luke 10:21.
This prayer of Jesus is incredibly revealing about the will of God (the Fathers "good pleasure"). It tells us that God hides from the proud ("the wise and learned") His great joy. But that God reveals to the believers ("little children") His great power, love and joy.
