Thy faithfulness is unto all generations: thou hast established the earth, and it abideth. (Psalms 119:90 KJV). He is ever faithful. A man can make a promise today only to wake up tomorrow and change his mind. Our God isn’t like this.
Unlike man, God is consistent and one-faced. He’s always true to His words, no matter the circumstance. He is ever faithful; he keeps promises. God is ever faithful. Trust him, and his promises will stand sure on you.
