When you claim to speak the message of God, but you do not deliver it with the temperament of Jesus, you distort our credibility.
Jesus was the fulfillment of the righteousness of God and was also the template for how that message is to be delivered to the people that need to hear it.
Jesus' message was not received well with everyone due to the hardness of their hearts, but your message is not received well because you are speaking to only one side of God's character (judgement) without displaying the attitude of Jesus (mercy and grace offered to those who do not deserve it).
That is why Jesus was the bridge; He spoke the Truth with authority AND embodied the mercy God extends to all. One without the other is not authentic.
