Musicians often speak of anxiety in terms of "performance anxiety" -- getting worried or excited about a performance, in a negative way.
The result is a general loss of focus resulting missed notes, forgotten passages, rushed tempos, and negative feelings about the experience. In the world of Music (as well as other worlds--sports psychology, public speaking, leadership, etc.) there's a micro-industry of folks who churn out books and seminars aimed at helping people control their performance anxiety.
The techniques commonly used often read like a handbook on Eastern philosophy. Breathing, visualization, hypnosis, mantras--all are found in the employ of conquering our performance anxiety.
In contrast, a Scriptural approach to anxiety seems to address the intellect (as opposed to 'the spirit' or our 'feelings' or 'emotions').
Two passages should suffice:
"...do not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God."
"...Look at the birds of the air: they neither sow nor reap nor gather into barns, and yet your heavenly Father feeds them. Are you not of more value than they?"
As we begin the Lenten season, we are reminded of a different type of anxiety--one far more foreboding than performance anxiety--an anxiety that is inculcated within us at the thought of Jesus' death, and our own deaths.
Let us be reminded in this penitential season that the 'cure' for all these anxieties is found in Scripture--in the clear, objective truths before us.
