"Say nothing but repentance unto this generation" (D&C 6:9, 11:9)
"In Biblical Hebrew, the idea of repentance is represented by two verbs: shuv (to return) and nicham (to feel sorrow)." (Wikipedia 7/28/2013)
What are we to say to this generation? Recognize that by your works you can do nothing. In your sorrow from His absence, turn towards God and face Him. Seek this Jesus of whom the prophets and apostles have written and begin to exercise faith.
