John 1:22-25 WEB
They said therefore to him, “Who are you? Give us an answer to take back to those who sent us. What do you say about yourself?”  He said, “I am the voice of one crying in the wilderness, ‘Make straight the way of the Lord,’ as Isaiah the prophet said.”  The ones who had been sent were from the Pharisees.  They asked him, “Why then do you baptize, if you are not the Christ, nor Elijah, nor the prophet?”
Pharisees are concerned with the rules. They are legalists. Pharisees went to John the Baptist and asked him who he was. They could recognize that he was anointed, but they could not discern his purpose. The Pharisees were more focused on being in control of John’s authority to act than they were interested in knowing what God was doing.
Pharisees had religious control of the region. John must have seemed like a threat to them. You can see in the passage how rude the Pharisees were to him. They demand he answer for himself. But, they had asked John a question only God could answer. Since Pharisees only got revelation from scriptures they walked away from John. They did not value that he was bringing people to repentance.
Lord Jesus, please help me know the Bible and practice its teaching while I keep my inner ear tuned towards your voice. In Jesus’ name, I pray, Amen
