"True Christian religion does not first present God in his majesty, as Moses and other teachers do. It commands us not to search out the nature of God, but to know his will presented to us in Christ, whom he wanted to take on flesh and be born and die for our sins; and he wants this to be preached to all the nations. 'For since is the wisdom of God the world in its wisdom did not know him, God was pleased through the foolishness of what was preached to save those who believe' (1 Corinthians 1:21). 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 our God's incomprehensible power, wisdom and majesty - how he created the world and how he governs it. If this is how you try to comprehend God, attempting 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 will 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.' (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 to 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."
-Martin Luther (Commentary on Galatians, pgs 34-35)
