Luk 5:22 But when Jesus perceived their thoughts, He answered and said to them, “Why are you reasoning in your hearts?
In Luke 5:22 Jesus is described as acquiring knowledge. This is contrary to claims that Jesus was omniscient (often claimed from prooftexts such as John 16:30). Jesus, in Luke, “perceives” events and thoughts as they occur in real time. He learns about them. The text doesn’t give the method of acquiring the knowledge. Jesus could have read their body language, heard their murmurs, or even had direct access to their thoughts. In any case, Jesus gains the knowledge.
