"But this doctrine, as it is understood by many, is, that Christians ought firmly to believe and trust in Christ, without spiritual sight or light, and although they are in a dark dead frame, and, for the present, have no spiritual experiences or discoveries. And it is truly the duty of those who are thus in darkness, to come out of darkness into light and believe. But that they should confidently believe and trust, while they yet remain without spiritual light or sight, is an anti-scriptural and absurd doctrine.
The Scripture is ignorant of any such faith in Christ of the operation of God, that is not founded in a spiritual sight of Christ. That believing on Christ, which accompanies a title to everlasting life, is a seeing the Son, and believing on him, John 6:40. True faith in Christ is never exercised, any further than persons behold as in a glass the glory of the Lord, and have the knowledge of the glory of God in the face of Jesus Christ, 2 Corinthians 3:18 and 4:6. They into whose minds the light of the glorious gospel of Christ, who is the image of God, does not shine, believe not, 2 Corinthians 4:5.
That faith, which is without spiritual light, is not the faith of the children of the light, and of the day; but the presumption of the children of darkness. And therefore to press and urge them to believe, without any spiritual light or sight, tends greatly to help forward the delusions of the prince of darkness. Men not only cannot exercise faith without some spiritual light, but they can exercise faith only just in such proportion as they have spiritual light. Men will trust in God no further than they know him; and they cannot be in the exercise of faith in him one ace further than they have a sight of his fullness and faithfulness in exercise.
Nor can they have the exercise of trust in God, any further than they are in a gracious frame . . . They that are in a dead carnal frame, doubtless ought to trust in God; because that would be the same thing as coming out of their bad frame, and turning to God; but to exhort men confidently to trust in God, and so hold up their hope and peace, though they are not in a gracious frame, and continue still to be so, is the same thing in effect, as to exhort them confidentially to trust in God, but not with a gracious trust: and what is that but a wicked presumption?" ~ Jonathan Edwards
