When Adam and Eve sinned, they not only broke their relationship with God but also damaged their relationship with each other. Humans have been struggling in relationship to one another ever since. Jesus is the answer to all types of disharmony. When we have received forgiveness in Jesus, we can forgive others (Ephesians 4:32). Jesus is the solution for our relational turmoil.
Jesus instructs His followers to love one another humbly, sacrificially and in unity (John 13:34–35).
