The Psalms do a beautiful job of teaching us that we can seek God with our whole heart and we can tell Him the truth all the time about everything. David does this in this Messianic Psalm 41.

4 O Lord,” I prayed, “have mercy on me.
Heal me, for I have sinned against you.”
5 But my enemies say nothing but evil about me.
“How soon will he die and be forgotten?” they ask.
6 They visit me as if they were my friends,
but all the while they gather gossip,
and when they leave, they spread it everywhere.
7 All who hate me whisper about me,
imagining the worst.
8 “He has some fatal disease,” they say.
“He will never get out of that bed!”
9 Even my best friend, the one I trusted completely,
the one who shared my food, has turned against me.
Psalm 41:4-9 NLT

Dear shepherd leader, you may be hurting because of the pain of betrayal but let this psalm be a reminder and an encouragement that David also lived through betrayal as did our Lord Jesus Christ. Our Lord and Savior has experienced everything that we have experienced and because He knows our pain let us take comfort in His mercy and grace. He loves us and delights in us.
