Yes, pain, disappointment, frustration, and anguish can be temporary scenes played out on the stage of life. Behind them can be a background of peace and the positive assurance that a loving Father will keep His promises.
No one wants adversity. Trials, disappointments, sadness, and heartache come to us from two basically different sources. Those who transgress the laws of God will always have those challenges. The other reason for adversity is to accomplish the Lord's own purposes in our life that we may receive the refinement that comes from testing. It is vitally important for each of us to identify from which of these two sources come our trials and challenges, for the corrective action is very different.
Sadness, disappointment, and severe challenges are events in life, not life itself. I do not minimize how hard some of these events are. They can extend over a long period of time, but they should not be allowed to become the confining center of everything you do.
I know that every difficulty we face in life, even those that come from our own negligence or even transgression, can be turned by the Lord into growth experiences, a virtual ladder upward. I certainly do not recommend transgression as a path to growth. It is painful, difficult, and so totally unnecessary. It is far wiser and so much easier to move forward in righteousness. But through proper repentance, faith in the Lord Jesus Christ, and obedience to His commandments, even the disappointment that comes from transgression can be converted into a return to happiness.
With the gift of the Holy Ghost comes the ability to develop a powerfully sensitive capacity to make the right choices. Cultivate that gift. As the Lord has said, that is accomplished by consistent, righteous living. As you enhance your capacity to sense the direction of that infallible influence, you will avoid disappointment, discouragement, and even tragedy.
