Knowledge does not equal obedience 

To have a healthy body: eat all nutritious meals, exercise your body, sleep 8 hours a day, stimulate your mind working, have social times, stay in a healthy weight, daily balance all these. 

Even though the world “knows “ this, the majority do not obey. And are therefore unhealthy to some extent. 

So it is with the Christian life. 

Knowing you are saved, forgiven, and made to be a tabernacle to serve as a light to the world, if not DOING is not being a full Christian. 

Faith without works is an unhealthy Christian indeed. 

We must obey to be what we are called to. 

Most Christians are non compliant and down right rebels. We need to come back to listening to God, submitting to his grace instead of resisting and let His life live through us. We cannot do it. Only by grace can we be what we were made for!
