GOD LOOKS INSIDE
John 4:19, "The woman saith unto him, Sir, I perceive that thou art a prophet."
This didn't take any great discernment on the woman's part. Jesus had just "read her mail". He told her the most intimate details of her life. Anyone could have perceived Jesus was a prophet after something like that.
This woman suddenly realized that she was dealing with more than just a man. God was speaking to her. What was her reaction? She changed the subject. She brought up a doctrinal issue concerning the proper place to worship--anything to get Jesus' attention off of her.
We all have a tendency to build walls of privacy around the intimate details of our lives. We are afraid to let anyone, especially God, look inside. But God already knows and He wants all of our heart.
Jesus brought this woman right back to the subject of her personal relationship with God. The place of worship or the forms of worship weren't important. God was looking for people who would open their hearts--even the hidden parts--for Him to inhabit.
Likewise today, Satan tries to get us occupied with everything except the one thing that counts. God wants us to worship Him in spirit and truth. Anything less than that is not enough.
