'Hidden' in the Bible

“You are the light of [Christ to] the world. A city set on a hill cannot be hidden;

At that time Jesus said, “I praise You, Father, Lord of heaven and earth [I openly and joyfully acknowledge Your great wisdom], that You have hidden these things [these spiritual truths] from the wise and intelligent and revealed them to infants [to new believers, to those seeking God’s will and purpose].

This was to fulfill what was spoken by the prophet:“I will open My mouth in parables;I will utter things [unknown and unattainable] that have been hidden [from mankind] since the foundation of the world.”
