The kingdom of heaven is for the heirs - and if children, then heirs; if born again, then heirs. Wherefore it is said expressly, Except a man be born again, he cannot see the kingdom of God. By this one word, down goes all carnal privilege of being born of flesh and blood, and of the will of man. Canst thou produce the birthright?
John Bunyan[Mr. Gifford] made it much his business to deliver the people of God from all those false and unsound rests that by nature we are prone to make and take to our souls. He pressed us to take special heed that we took not up any truth upon trust - as from this or that, or any other man or men - but to cry mightily to God that He would convince us of the reality thereof, and set us down therein by his own Spirit in the holy word.
