'Word of God' in the Bible

Because by them the true word of God was changed into that which is false, and they gave worship and honour to the thing which is made, and not to him who made it, to whom be blessing for ever. So be it.

For this is the word of God's undertaking, At this time will I come, and Sarah will have a son.
