God is a God of integrity. Whatever He says He will do for He doesn’t violate what He has spoken. When He says it, surely we can count on it.
His Word is the truth. His Word is His bond. Whoever He says He is in His Word, that is Who He is.
God is not a man, that He should lie; neither the son of man, that He should repent: has He said, and shall He not do it? or has He spoken, and shall He not make it good? (Numbers 23:19)
