Those who are born of God…
1. Keep his commandments (2:3-4; 3:24)

5. Confess the Son and receive (have) him (2:23; 4:15; 5:12)
6. Practice righteousness (2:29)
7. Don’t make a practice of sinning (3:6; 3:9-10; 5:18 )
8. Possess the Spirit of God (3:24; 4:13)

Already Not Yet 
Thanks for these evidences and the conviction that followed. Leave it to Piper to let the Scriptures do surgery on my soul.
Oh, I can see I’m going to enjoy reading this blog!
I’ve only just dipped my toe in the water and uploaded my first tentative paragraphs on WordPress – many of my interests coincide with yours, Peter, and I too am a Chiristian who has found real freedom in the grace of a loving God. I am also a great fan of the challenging and provoking writings and videos of John Piper.
Good to see you here!
