'Children of God' in the Bible

For as many as are led by the Spirit of God, these are children of God.

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

For the creation waits with eager expectation for the children of God to be revealed.

For nature was subjected to imperfection, not by its own will, but by the will of Him who thus made it subject??21 yet not without the hope that some day nature itself also will be freed from the thralldom of decay, into the freedom which belongs to the glory of the children of God.

Because the creature itself also shall be delivered from the bondage of corruption into the glorious liberty of the children of God.

That is, They which are the children of the flesh, these are not the children of God: but the children of the promise are counted for the seed.
