filling of the holy spirit

The great difference between present-day Christianity and that of which we read in these letters, the New Testament epistles, is that to us, it is primarily a performance; to them it was a real experience. We are apt to reduce the Christian religion to a code or, at best, a rule of heart and life. To these men it is quite plainly the invasion of their lives by a new quality of life together. They do not hesitate to describe this as Christ living in them.
