Last Adam is the Christian belief that Jesus was the last person to be born on Earth who was also the perfect representation of God. This means that Jesus was the last of God's creations who showed perfect obedience and love to God and showed us how we should live our lives. Jesus is also believed to be the only way to salvation, which means that through him, believers can get to Heaven and have an eternal life with God. In other words, Jesus is the only one who can help us get to Heaven, if we follow him and live our lives according to God's will.
