“Jesus is the central aspect of humanity’s change in relationship with God.”
Relationships are tricky. I don't think it's an overstatement to say that every person alive has had to deal with at least one relationship that was, well, complicated! It stands to reason that if our human relationships are complex, then our relationship with God will also be tricky, and scripture bears this out.
How to have a relationship with God is a question of significant concern for many of the New Testament books (actually for the Old Testament too - relationship problems between God and humanity start in the first chapters of Genesis). The Jewish people thought they had it figured out, and for a while, they did. Then Jesus came along and changed everything by redefining how humanity was to relate to God. This was excellent news, even if it didn't seem like it to the Jewish authorities.
The message of the Gospel, the message of primary concern for Jesus, was that everyone could be in a relationship with God - everyone! The old walls of inclusion and exclusion didn't exist any longer because the actions Jesus took applied to every man, woman, and child who ever lived. The outcome of Jesus' sacrificial death and resurrection meant that each person believing in Jesus could be "made new" or "made right" by dying to their old self, the self that constantly rejected God and was dirtied by all that rejection. That person is then re-born with Jesus through faith, and because of Jesus' resurrection, those who have faith are new without the stain of the previous way of life or thinking. Pretty great, right?! Then we are gifted the spirit of God to help us in this new way of life.
Jesus is the central aspect of humanity's change in relationship with God. Meaning humanity doesn't have to strive to overcome the disconnection with God through some effort or special knowledge; we don't have to ascend to the heavens by enlightenment or the emptying of ourselves so that we can perceive the dive. One of the most beautiful aspects of the Christian faith is that God sought us. He came for you; he came for me; he came for all creation. He let us hear his voice, see his face, and experience his love. He came to show us that he loves us and wanted to fix things, to give us all hope and invite us into a deeply meaningful relationship.
Galatians 3:26-29 says, "For you are all children of God through faith in Christ Jesus. And all who have been united with Christ in baptism have put on Christ, like putting on new clothes. There is no longer Jew or Gentile, slave or free, male and female. For you are all one in Christ Jesus. And now that you belong to Christ, you are the true children of Abraham. You are his heirs, and God's promise to Abraham belongs to you."
Yes, relationships are tricky, but the good news of the Bible - the entire story of the Bible - is that God wants to be in a relationship and that he made a way for that to happen. The question we have to wrestle with is one of response. I hope relationship with Jesus is something you will consider. You were made for this relationship - it's how you were designed. His invitation is an open one, my advice - don't wait!
Romans 7:4,6: "So, my dear brothers and sisters, this is the point: You died to the power of the law when you died with Christ. And now you are united with the one who was raised from the dead. As a result, we can produce a harvest of good deeds for God...But now we have been released from the law, for we died to it and are no longer captive to its power. Now we can serve God, not in the old way of obeying the letter of the law, but in the new way of living in the Spirit."
