Brennan Manning writes that Christians who do not walk the talk can is a primary reason why there are atheists among us...
"The single greatest cause of atheism in the world today is Christians, who acknowledge Jesus with their lips, then walk out the door, and deny Him by their lifestyle. That is what an unbelieving world simply finds unbelievable" (Free at Last: The Movie)
Simply put, we are to live the life. Jesus made that clear in Matthew 5.16: In the same way, let you light shine before others so that they may see your good works and give glory to your Father who is in heaven (ESV)
If Manning is correct in his assessment, then not only do we need to live as Jesus intended; but we also need to pray that we will shine the light of Jesus and that the Holy Spirit will transform hearts as we do shine. Does that make sense?
Have a great day
