How are Christians meant to respond to the antagonism of an unbelieving world... Meekness. Don't be fooled and confuse meekness with weakness though. Jesus gave us a perfect model for meekness in the Garden of Gethsemane - strength and power - under control and submitted to God's will.
When we are filled with and trust in the power of Jesus Christ we can respond to a world with true Christ-like meekness
