The big idea

I've been trying to boil down the overall message of the Bible in way that is clear, memorable and relevant to youth.  I want something that I can continually point to and say, "Here's the big idea.  Here's what God is up to in the world.  Here's what God is calling you to do."  Here's what I've got so far. 

God is on a mission to rescue people from sin, darkness and death and to bring them into his love and eternal life! 

Therefore:

Have you been rescued by trusting in Jesus as YOUR God (that which is most important) and YOUR Savior (that which is most needed)?

If so, God has called you to be a part of his mission to rescue others?  Your work is not done; you have a mission from God.
