Wrong. The branch in vs 2 is lifted up and supported [Greek airei from airō (to lift)] if it does not bear fruit and if it does bear fruit the branch is cleansed (wiped clean). Branches are lifted up/supported and/or cleansed so that the branch may bring forth more fruit.
Every branch in me that beareth not fruit he [airei from airō (to lift)]: and every branch that beareth fruit, he purgeth it, that it may bring forth more fruit.
Your understanding of the verse is that only the branch that bears fruit is tended to so that it may bring forth more fruit. The wonderful truth set out in John 15:2 is that the branch that is not bearing fruit and the branch that bears fruit are declared by the Lord Jesus Christ to be in me. Both branches are abiding in the Vine. The Husbandman does not rip the believer (branch) who is abiding in the Lord Jesus Christ away from the Vine.
such a wonderful description in scripture of how God works
it is compelling and and speaks to us of the faithfulness of our God
so sad that the deceitfullness of satan works through some to diminish the beautiful words of Jesus and to cast doubt on God's ability to keep those who are His!
but we know who the victor here is and His Name if FAITHFUL AND TRUE!
