"I will give you the keys of the kingdom of heaven: whatever you bind on earth shall be bound in heaven; and whatever you unbind on earth shall be unbound in heaven.”
There are levels of knowing the person. The lever gets higher as people shares more and more in each other’s life. This process of knowing takes time. Jesus, after having some time with His apostles and doing His public ministry wants to validate how people perceive Him. He turned to His apostles for information. Who do people say He is in front of all that He has done already. The answers were varied. They could not put their finger exactly as to His person. One thing clear is that they know He is not an ordinary man. And then the surprise question, who do His followers think He is. That day both Jesus and disciples were mutually surprised. The disciples because Jesus forced them to disclose their heart relative to Him, and Jesus because the disciples have such deep insights into His personhood.
