A tricky subject that not many people understand, especially in a Biblical view.
Self Control is the ability to control yourself. Mostly based on emotions that you have.
If we don’t let the Holy Spirit in, it is hard for us to have proper Self Control.
We must have Self Control if we are to follow Christ. As Christians we are called to be Christ-like and be the example of what our Lord wants us to be (His People). Though it is tough, we have to read, listen, and pray to be more like Him and that starts with Self Control.
