'Untaught' in the Bible

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].

In that very hour He was overjoyed and rejoiced greatly in the Holy Spirit, and He said, “I praise You, O Father, Lord of heaven and earth, that You have hidden these things [relating to salvation] from the wise and intelligent, and have revealed them to infants [the childlike and untaught]. Yes, Father, for this way was [Your gracious will and choice, and was] well-pleasing in Your sight.

But if all prophesy [foretelling the future, speaking a new message from God to the people], and an unbeliever or outsider comes in, he is convicted [of his sins] by all, and he is called to account by all [because he can understand what is being said];

He speaks about these things in all his letters in which there are some matters that are hard to understand. The untaught and unstable twist them to their own destruction, as they also do with the rest of the Scriptures.
