Matt 22:29 Jesus answered and said to them, “You are mistaken, not knowing the Scriptures nor the power of God.”

Jesus is responding to a question about Jewish Law concerning marriage and raising children for a brother through the brother’s widow.
The group bringing the question, the Sadducees, were not interested in an answer about the Law as much as an answer from Jesus.
It’s ironic for the Sadducees, who do not believe in the resurrection (Matt 22:23), to ask a question about the resurrection.
Jesus’ first response suggests the answer is readily available to them through the scripture but they refuse to search and learn, allowing their own prejudice and doctrine to dictate their beliefs.
My concern for myself and the church is centered around the same thought.
Do I let what I’ve been taught through the years determine what I believe to be true?
I know my beliefs have changed through the years due to more study of the scripture.
I am still learning since I am unwilling to simply take someone’s word on it.
It’s a good practice for Christians.
When Paul preached Jesus to the Berean Jews, they searched the Scriptures daily to find out whether these things were so. Acts 17:11
We should do the same.
