@ The purpose
God made a good, beautiful world filled with beings to share in this life of joy and peace by knowing, serving, and loving God and one another.
@ The problem
Instead, we chose to center our lives on ourselves and on the pursuit of things, rather than on God and others. This led to the disintegration of creation and the loss of peace within ourselves, between people, and in nature itself.
@ The solution
God entered history in the person of Jesus to deal with all the causes and results of our broken relationship with him. Jesus lived the life we were created to live and then died to pay the debt of sin incurred for the life we actually live. By his resurrection he showed that death is now defeated and he showed us the future- new bodies and a completely new heaven and new earth, in which the world is restored to full joy, glory and peace.
