If we believe not, He continueth faithful, He can not deny Himself. 
2 Timothy 2: 13

God is not a man, that He should lie, nor as the son of man, that He should be changed. Hath He said then, and will He not do? hath He spoken, and will he not fulfill? 

Numbers 23: 19

For men swear by one greater than themselves: and an oath for confirmation is the end of all their controversy. Wherein God, meaning more abundantly to shew to the heirs of the promise the immutability of His counsel, interposed an oath: That by two immutable things, in which it is impossible for God to lie, we may have the strongest comfort, who have fled for refuge to hold fast the hope set before us. 

Hebrews 6: 16-18
