Just as Jesus sharing the water of life to the Samaritan woman at the well (John 4), the church built by Jesus will be "messy" as she will be comprised of people from different backgrounds. We are to follow Jesus' example in acknowledging sins, but don't let those sins keep us from sharing the love and goodness of Jesus Christ.
We are reminded of the significance of Jesus' Resurrection. It is an unprecedented and undeniable proof of Jesus' power. His resurrection was God's acceptance of His sacrifice as payment for our original disobedience, which led to the consequence of mankind's spiritual death. As we chose to accept Jesus, we will have freedom and spiritual life for all eternity.
