Numbers 23:19 God is not a man, that He should lie, Nor a son of man, that He should repent; Has He said, and will He not do it? Or has He spoken, and will He not make it good?
Men will lie to you for their own sinful reasons and then would have to ask for your forgiveness because of their sin. God is not a man and does not need to lie to you. Instead He is faithful and true, so if He promised you something, God will do just what He said He would do for you. Count on it.
