As you pray salvation for others, pray that you will have a heart that’s pure, untainted by evil; a steadfast,willing spirit; the Holy Spirit’s presence; and the joy of salvation.
If you have those things, then you can teach others to turn back to God (see Psalm 51:10-13).

Yes, I’ve been reading Psalm 51 all summer. I saw this today.
