Through Christ we are enlightened to understand the works of God :
We understand nothing of the works of God, if we do not take as a principle that He has willed to blind some and enlighten others. (Pascal, 566)
How do we know the works and will of God? We turn to scripture.
In scripture we learn that God has created the world, redeemed the world, controls the cosmos, and loves His people. As the only infinite, immortal, invisible, omniscient, and omnipresent being, we should obey him.
"I call heaven and earth to record that I have set before you life and death, that you should choose life, and love God, and obey Him, for God is your life." (Deut. 30:19)
If there is a God, then we have much to fear, much to love, and much to do. If there is a God then we should want to know what he requires of us. Again, Pascal clarifies for us:
Let us now take the will of God; all that He wills is good and right to us, all that He does not will is bad. All that God does not permit is forbidden... But so long as God does not permit it, we ought to regard it as sin; so long as the absence of God's will, which alone is all goodness and all justice, renders it unjust and wrong. (Pascal, 668)
What does God will for us to do? That question is one that we should be continually asking ourselves. The pursuit of the will of God is a worthy life-long pursuit.
Isaiah admonishes us: “Learn to do right, seek justice, defend the oppressed, take up the cause of the fatherless, plead the case of the widow.” (Is. 1:17)
Christ challenges us: “Go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you.” (Mat. 28:19-20)
