Christ is shown in Revelation to be a King. He is the Head of the churches clothed in majesty and having authority. He judges with his eyes of fire and the Word of God in His mouth. Jesus has the voice of power. He shines in His glory.
While Jesus shows us His kind, gentle, humble, loving, meek, peaceful and forgiving side as a man.
It evokes a Godly fear and a humble heart in the reader. Because this Almighty King became a man and was obedient unto death on a cross for a world of lost sinners who didn't know Him. And He is declaring His expectations of our lives before Him. There is a penalty to those who won't heed His Word or a blessing for those who overcome.
We need to understand Jesus of Galilee to understand we have grace and forgiveness when we fail. And yet we must understand Jesus the King whom we are servants of so that we aren't comfortable with sin. We have to strive to be like Him and depend upon His help to get us there.
