Every heretic claims that. How you do you know that you're not one of them?
-A8
Well to you, apparently I am. How do you know that YOU have it right? For myself, my appeal is to Scripture. How do YOU know that what you believe is right? To what do you appeal?
Romans 8:15-17 (King James Version)
15For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father.
16The Spirit itself beareth witness with our spirit, that we are the children of God:
17And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together.
