Those who follow Christ will take up their cross deny themselves and follow Him. The cross is about self denial. It is the continual denial of the flesh for Christ condemned sin in the flesh. His death on the cross was the supreme manifestation of self denial and love for the world.
The Gospel process is expressed in John 16:8. A Conviction of Sin, righteousness and Judgement. These three steps are expanded in Matt 5:1-11 and also in the three parts of the Sanctuary.
