I wonder if your friend really wanted to cut ties with you or did they have pressure from a elder who noticed it? The elders get involved with sabotage of friendships because they have nothing better to do, I know elders who would only check up on Witnesses if they heard they were associating with "unhealty influences", so maybe those words don't belong to your friend but a special person or elder who decided your friend needed to cut you off.
So much for doing good to everyone! 1 Thes 5:
9-11 God didn’t set us up for an angry rejection but for salvation by our Master, Jesus Christ. He died for us, a death that triggered life. Whether we’re awake with the living or asleep with the dead, we’realive with him! So speak encouraging words to one another. Build up hope so you’ll all be together in this, no one left out, no one left behind. I know you’re already doing this; just keep on doing it.
The Way He Wants You to Live
12-13 And now, friends, we ask you to honor those leaders who work so hard for you, who have been given the responsibility of urging and guiding you along in your obedience. Overwhelm them with appreciation and love!
13-15 Get along among yourselves, each of you doing your part. Our counsel is that you warn the freeloaders to get a move on. Gently encourage the stragglers, and reach out for the exhausted, pulling them to their feet. Be patient with each person, attentive to individual needs. And be careful that when you get on each other’s nerves you don’t snap at each other. Look for the best in each other, and always do your best to bring it out.
16-18 Be cheerful no matter what; pray all the time; thank God no matter what happens. This is the way God wants you who belong to Christ Jesus to live."
