A pure heart produces awesome Spiritual fruit. Be willing to joyfully let go of everything else in-between. The Holy Spirit does all the change work within us when we remain willing to be willing to be changed into what is changeless, consistently.
1 Timothy 1:5-7
5 Whereas the object and purpose of our instruction andcharge is love, which springs from a pure heart and a good (clear) conscience and sincere (unfeigned) faith.
6 But certain individuals have missed the mark on this very matter [and] have wandered away into vain arguments and discussions and purposeless talk.
7 They are ambitious to be doctors of the Law (teachers of the Mosaic ritual), but they have no understanding either of the words and terms they use or of the subjects about which they make [such] dogmatic assertions.
