Proof positive
1 John 2:29 If you know that He is righteous, you know that everyone who practices righteousness is born of Him.
The apple wont fall far from the tree. As I practice righteousness, thats a living walk in Gods truth, there is proof Im born again. My natural man, the flesh, doesnt walk or practice righteousness on its own. Im a new creation, old things are passed away, Ive been born again! The desires I once had, that ruled over me, I was enslaved to, has been nailed to the cross. Im lead into righteousness as He leads me by His Spirit.
