In Galatians 4 Paul compares two sons that were born from two different women from Abraham.  One son was born according to the flesh/in a natural way, the other son was born according to promise/the spirit (v.23, v29).  What does he mean by this?

The son born according to the flesh was born a slave.  The son born according to the promise was born free.  Paul then goes on to say that were are not children of the slave, but of the free woman (v.31).  What do you think it means to live as a child of the flesh? what do you think it means to live as a child of promise? 

Are there any times recently that you know you've lived as a child of the flesh?

Are there anytime recently that you know you've lived as a child of promise? 

How can the group pray for specifically to live more as a child of promise?
