Let's assume the following verses are really true ...and see what that means for us in the middle of all the annoyance, panic and bother and other overloaded feelings you are probably going through:
In everything we have won more than a victory because of Christ who loves us.
I am sure that nothing can separate us from God's love--not life or death, not angels or spirits, not the present or the future, and not powers above or powers below.
Nothing in all creation can separate us from God's love for us in Christ Jesus our Lord!
From Romans chapter 8 in the Bible
What can separate us from God's love; apparently ...nothing...that includes work, study and exams. Take heart!
