but I know you: you do not have the love of God within you.
In context
40yet you refuse to come to me and have life. 41I do not accept glory from human beings, 42but I know you: you do not have the love of God within you. 43I have come in my Father’s name, and you do not receive me; if someone else comes in his own name, him you will receive. 44How can you believe, when you accept glory from one another and do not seek the glory that comes from the only God?
