It may be hard to believe, but you can have joy after a loss.

“Our soul waits for the Lord; He is our help and our shield. For our heart shall rejoice in Him, Because we have trusted in His holy name. Let Your mercy, O Lord, be upon us, Just as we hope in You. Psalm 33:20-22

Joy is a fruit of the spirit.  To receive the fruit, we must submit to God.

We depend on God; he is everything we require in life. Joy is the settled assurance that God is in control of all the details of your life, the quiet confidence that ultimately everything is going to be alright, and the determined choice to praise God in every situation.
