Happiness is a Conscious Decision

Yes, we find happiness in the midst of the trial of our faith. The Lord manifests Himself to us through His tender mercies, which we find along the road of happiness. We see with increased clarity His hand in our lives.

Happiness is a condition of the soul. This joyous state comes as a result of righteous living.
