When we face difficult times, we too can feel that no one hears. And worst of all, we can feel that God Himself doesn't listen to our cries or see our tears. But He does! And that's why we need the language of petition and protest found especially in the book of Psalms. The Psalmist petition for God's help and also protest their situation to Him. In Psalm 61 - David brings his petitions and protests before his Creator; stating...I call to you, I call as my heart grows faint, lead me to the rock that is higher than I. David cries out to God because he knows that only He is his refuge and strong tower.
Praying the petitions and protests of the psalms is a way of affirming God's sovereignty and appealing His goodness and faithfulness. They're proof of the intimate relationship we can experience with God. In difficult moments, we can all be tempted to believe the lie that He doesn't care. But He does. He hears us and is with us.
