Hmm,wow as for those that have receive Jesus are save once and for all,there are people that profess Jesus but are not born again like the seven seven sons of sceva,John 3:17 For God sent not his Son into the world to condemn the world; but that the world through him might be saved. 3:18 He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.
And also God knows us his children,Galatians 4:9 But now, after that ye have known God, or rather are known of God, how turn ye again to the weak and beggarly elements, whereunto ye desire again to be in bondage?
