Well your statement was so mixed up so am not sure of what you are asking.
You missed the whole point Jesus was sent by God to this earth for one purpose, but filled many purposes. He was sent to be crucified(sacrifice in other words, Lamb of God) so that we could have eternal life through the shedding of his blood.
He also defeated the devil. For God loved the world so much that he gave his only Son, that we might have everlasting life through the Son. Because this had to come true, to accomplish this purpose. The people that were not truly of God did not believe him to be who he was because they were not of God.
The ones that did believe him and were of God listened and learned from him. They preached the "good news" and showed others what his words meant.
But just like today many read the Scriptures, but no not the Lord. They preach his word, but do not live his word. To really accept Jesus you have to do it in your heart, and follow the righteous path.
Love one another as I love you. Means to love everyone, but it does not mean to love evil or condone the evil they do. You can still love a person, and hate what they do.
Jesus did not condone the pharisees or love what they did. The pharisees are the actual ones that crucified him. They sought human recognition and praise and exalted themselves.
