Wheat or tare?

1 John 2:19 They went out from us, but they were not of us; for if they had been of us, they would have continued with us; but they went out that they might be made manifest, that none of them were of us.

There are those few, tares, that grow up in the midst of the wheat. They appear to be wheat yet thats as far as they go. Ive learned, if you listen to them talk long enough, its evident to whom they belong. I want my life to reflect Christs! Judas even followed Jesus for several years and we know his end. Eventually, Christ & His agenda wont be sufficient enough thus they move on. I just have to say, Jesus You are more than enough! Where else can I go? You have the words of life!
