A real influence!

(Letters of John Newton)

"Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come." 2 Corinthians 5:17

The saving grace of God has a real influence upon the whole man. It . . .
  enlightens the understanding,
  directs the will,
  purifies the affections,
  regulates the passions, and
  corrects the different excesses to which different people are by constitution or habit inclined. It does not impart any new natural powers, though it teaches the use and improvement of those we have received.
