If you are someone who has ever experienced the fickleness of human friends or family, there is someone you can trust.
Balak (king of Moab) was trying to get Balaam to curse the Israelites. Since Balaam would only speak the words God put in his mouth, Balak learned that the Lord would not turn His back on his promises to Israel:
God is not human, that he should lie,
not a human being, that he should change his mind.
Does he speak and then not act?
Does he promise and not fulfill?
(Numbers 23:19-20, NIV)
There is One who cannot be tempted to betray you. Trust in Him.
