Galatians 5:22-23 New International Version (NIV)
22 But the fruit of the Spirit is love, joy, peace, forbearance, kindness, goodness, faithfulness,23 gentleness and self-control. Against such things there is no law.
John 13:34-35 New International Version (NIV)
34 “A new command I give you: Love one another. As I have loved you, so you must love one another. 35 By this everyone will know that you are my disciples, if you love one another.”
If LGT or what ever form of perfection teaching, actually increased the fruit of the Spirit in peoples lives I would think there might be something to it. But I haven’t seen it do that. If it can’t do that, what hope does it have for reaching “perfection”?
