"For the word of God is living and powerful, and sharper than any two-edged sword, piercing even to the division of soul and spirit, and of joints and marrow, and is a discerner of the thoughts and intents of the heart." Hebrews 4.12
It's the only word capable of generating power to create, save and transform any human being. God does not require perfection, holiness, purity or any other virtue. Only a vote of confidence that He will do everything He promised to do. Those who propose themselves to believe in it will have the Personal Answer from the Almighty.
