Jesus accomplished all of the points mentioned here, among other things.
Jesus demonstrated God's love through His sacrifice on the cross. Jesus said that "greater love has no one than this, that he lay down his life for his friends". The sacrifice of Christ on the cross is further demonstration of God's unimaginable lovingkindness.
Jesus certainly brought the Good News to the poor in spirit. No longer would we be shackled by the yoke of the Law and salvation does not lie in our deeds or how accurately we followed the Law, but was available to us through belief in Him.
Jesus sacrificed himself for others and we were sacrificed with Him. Through our belief in Jesus Christ as our Savior our old selves are put to death and we are born again as children of the Most High God.
Abundance of life is an undeserved gift from God to those who are in Him. The very fact that you took a breath this morning when you woke up us evidence of his abundant grace. If we accept Christ and live in Him our lives will be abundant. Maybe not in material wealth and things, but certianly our lives are blessed and we are enabled to share the Good News.
Jesus tried to get everyone to understand the Kingdom of God for three years. He was partially successful in person, but left his disciples to complete the task. This will always be an in-process commandment until Christ comes again. we, as disciples must carry out the Great Commission and spread the Gospel.
Jesus changed the world forever with only three years of ministry. The words of Christ and the Word of God remain today just as they did thousands of years ago. He showed the world that the only way to salvation is through Him and to obtain it, all we have to do is believe and accept Him.
