Taking a look at Western Christianity, most who claim to be Christians are not making a significant impact on the people around them. Instead of influencing the world for God through their lives, as Christ says believers will in Matthew 5:13-16, the majority have assimilated to the culture to the point that their lives are undistinguishable from anyone else’s.
Jesus not only laid out His expectation of personal and cultural impact, He also set the example for us. So, why aren’t Christians acting like Jesus?
“The primary reason that people do not act like Jesus is because they do not think like Jesus. Behavior stems from what we think –our attitudes, beliefs, values, and opinions,” - George Barna, in Think Like Jesus.
