If we all like the idea of unity, why is achieving it so hard? 

Unity does not come naturally to fallen human beings (4.17-19)

• Apart from God, we are all the problem people. 
• Apart from God, there can never be lasting unity.

The Prerequisites of Unity (4.20-24)

• Unity is only possible when we are first made new in Christ 
• We need God to rewrite our software. 

A New Way of Life (4.25-32)

• Choose to live according to your new software. 
• Choose to build others up (4.29). 

Take Home Idea: We are better together when we live according to the new attitude of mind that we all have in Christ Jesus
