If you continue in known and unconfessed sin, no one can tell you at what point you cease to become a follower of Jesus and again become part of Satan's Kingdom.
Kung magpatuloy ka sa kasalanang nalalaman mo at hindi nagsisisi, walang makapagsasabi sa iyo kung kailan ka huminto sa pagsunod kay Jesucristo at muling naging bahagi ng Kaharian ni Satanas.
