Romans 8:16

Romans 8:16. The Spirit itself beareth witness with our spirit, that we are the children of God:

Many of you make a profession of being the children of God. Can your own spirit say that it is true? And is there, in addition to the witness of the Spirit within you that it is true? If not, unless there is a witness to our testimony, it avails nothing. Our Lord Jesus Christ said, "If I bear witness of myself, my witness is not true"; and if he chooses to put himself on a level, as it were, with the rest of humanity in that respect, we cannot expect that our witness will stand for ought if it stands alone. No, there must be the Spirit himself bearing witness with our spirit that we are the children of God.
