It is good every so often to write as clear a description of the gospel of Jesus Christ as possible.  Here is one attempt:

 The One True God created the universe and He made it good.  He made man in his own image, put him into the world, and gave him charge over the earth.    But man rebelled against God.  Men wanted to be in charge and be their own god.  Because of this sin, the whole creation was cursed.  The curse is so bad and so deep that there is nothing any of us can do to redeem ourselves.  (Genesis 1-3)

 Ever since the curse, all of the rest of history is about the One True God’s plan for redemption of creation.  (Rest of the Bible)

 At just the right time, God sent Jesus Christ, who was fully God and fully man, sinless and righteous, to provide redemption.  The right time included the establishment of monotheistic Judaism at a world crossroads.  Most people knew Greek and could communicate with each other.  The Romans had built safe and reliable roads.  The good news could be spread by trusted witnesses. 

 Jesus was unjustly sentenced to death and crucified on a cross by sinful men.  What men intended for evil, God intended for good.  At the crucifixion, a trade occurred.  Jesus took all our sins upon himself and we received Jesus’ righteousness.  (Matthew, Mark, Luke, John, Acts)

 God’s kingdom has come; it continues to grow as God rescues more people through His mercy.  The Re-Creation will occur and the curse will be completely lifted in the future when Jesus returns, the current earth is destroyed, and a new heaven and new earth are revealed.  It will be VERY good.  (Revelation)
