What if you were not anxious? Does anxiety accomplish anything, except for resulting in sickness? Did Jesus become anxious before or during His going to the cross? How about anticipating the result of your internship as being successful. That is certainly more mind clearing and healthy than anxiety. Anxiety hinders you and can result in poor performance. Keep your mind on the Word and all the goodness of God. With God you cannot fail, now matter what you do. With God all things work together for good. But you have to keep up your end of the bargain, by loving God and keeping your mind on Him, and not your circumstances.
In the name of Jesus, I bless you with the life of God.
