Be thankful to Jesus, Be a witness to His great Works through academics exploring His creation

Be thankful in a meaningful way:
"...What this one medical missionary found out was that instead of saying thank you, what the people would say instead, was the equivalent of, "I will share your name." So, everywhere they went, they would tell the missionary's name and what he had done for them. Jesus says, in Luke 9:26, for us not to be ashamed of him and what he has done for us. I know there are some tough places where it will be hard for us to share His name. But the thing that the Lord wants you to do is to share His name along the way."
~Beaver Baptist Church
Study even if you feel these are the last days:
"The other person I want to mention is C.S. Lewis. On October 22, 1939, he preached at the University Church of St. Mary the Virgin in Oxford. Less than two months earlier Hitler had invaded Poland, and Britain was about to face the horrible onslaught of the Nazi attack known as the Battle of Britain. This is what C.S. Lewis told the assembled students:
It may seem odd for us to carry on classes, to go about our academic routine in the midst of a great war. What is the use of beginning when there is so little chance of finishing? How can we study Latin, geography, algebra in a time like this? Aren’t we just fiddling while Rome burns?
This impending war has taught us some important things. Life is short. The world is fragile. All of us are vulnerable, but we are here because this is our calling. Our lives are rooted not only in time, but also in eternity, and the life of learning, humbly offered to God, is its own reward. It is one of the appointed approaches to the divine reality and the divine beauty, which we shall hereafter enjoy in heaven, and which we are called to display even now amidst the brokenness all around us.
Graduates, this is your calling too. Amidst the brokenness all around us, and sometimes even within us, we are summoned today to be faithful to God’s calling. We are to be steadfast, persevering in discipleship so as to bear witness to the beauty, the light, and the divine reality that we shall forever enjoy in heaven. We are called to do this in a culture that seems, at times, just like Augustine’s—a fragile world beset by dangers we cannot predict. You will not do this perfectly—you will fail, as all human beings do—but reach out and claim the promise of God’s forgiveness. Reach out and accept the gift of a new beginning, the stewardship of starting all over again.
As Augustine thought about the world, the culture, and the civic institutions, like an old man tottering and about ready to die, he said:
Are you surprised that the world is losing its grip? That the world is grown old? Don’t hold onto the old man, the world; don’t refuse to regain your youth in Christ, who says to you: “The world is passing away; the world is losing its grip; the world is short of breath. Don’t fear, your youth shall be renewed as an eagle.”
