“So, when your conscience is in conflict, wrestling against the law, sin, and death, in the presence of God, there is nothing more dangerous than to wander amidst curious heavenly speculations, searching out God’s incomprehensible power, wisdom, and majesty - how he created the world and how he governs it. If this is how you attempt to pacify him without Christ the mediator, making your works a means between him and yourself, you will fall as Lucifer did and in horrible despair lose God and everything else. God is in his own nature immeasurable, incomprehensible, and infinite, and so human nature finds him intolerable.
If you want safety, then, to flee from perils of conscience and salvation, bridle your presumptuous spirit, and seek God in the way that Paul teaches: ‘We preach Christ crucified, a stumbling block to Jews and foolishness to Gentiles, but to those whom God has called, both Jews and Greeks, Christ the power of God and the wisdom of God' (1 Corinthians 1:23-24). So begin where Christ began - namely, in the womb of the virgin, in the manger, at his mother’s breast. The reason he came down, was born, lived among men and women, suffered, was crucified, and died was so that he might present himself plainly to our eyes and fasten our spiritual sight upon himself, so that he might keep us from climbing into heaven and from the curious searching of the divine majesty.
Whenever you are dealing with the matter of justification, therefore, and are wondering where and how to find God who justifies and accepts sinners, remember that there is no other God besides this man, Christ Jesus. Embrace him, an hang on to him with your whole heart, setting aside all curious speculations about the divine majesty. Those vain people who exclude the Mediator do not believe this. Christ himself says, ‘I am the way and the truth and the life. No one comes to the Father except through me’ (John 14:6). Therefore, apart from Christ you will find no other way to the Father, but only wandering: no verity, but hypocrisy and lying; no life, but eternal death. Take careful note, then, that when any of us has to wrestle with the law, sin, death, and all other evils, we must look to no other god, but only this God, incarnate and clothed with human nature.”
-Martin Luther, Galatians, p. 34-35.
