Matthew 19:16-22 - You can’t do a good work to earn eternity and you cannot do a bad work to dis-earn eternity. God forgives and transforms people from the inside out. If you cannot earn salvation based on your works then Biblically you cannot lose salvation based on your works. We are born into God’s family at the point of salvation. No where in the Bible does God kick a child of His out of His family and send them to the lake of fire forever!
