Luke 10: 21 - 24
21 In that same hour he rejoiced in the Holy Spirit and said, "I thank thee, Father, Lord of heaven and earth, that thou hast hidden these things from the wise and understanding and revealed them to babes; yea, Father, for such was thy gracious will.
22 All things have been delivered to me by my Father; and no one knows who the Son is except the Father, or who the Father is except the Son and any one to whom the Son chooses to reveal him."
23 Then turning to the disciples he said privately, "Blessed are the eyes which see what you see!
24 For I tell you that many prophets and kings desired to see what you see, and did not see it, and to hear what you hear, and did not hear it."
