"Stir My Heart" is a song by Sara Groves that reflects on the challenges and doubts we face in life, especially in relation to our faith. The lyrics describe the narrator's desire for God to intervene and restore their passion, faith, and joy in the face of time, circumstances, aging, fear, doubt, and pain. The song acknowledges that it is easy to fall off track and lose sight of one's beliefs and convictions. The narrator asks God to awaken their heart and rekindle the fire within, reminding them of the initial joy and desire they had when they first encountered God. The lyrics also touch on the potential influences of others, the struggles of standing strong in the face of trials, and the danger of being misled and doubting God's truth. The narrator expresses their resolve not to let these things happen to them, drawing a parallel to Peter, who famously denied knowing Jesus three times before the rooster crowed. Ultimately, the song is a prayer for guidance, strength, and a deep connection with God. It speaks to the universal human experience of wrestling with doubt, fear, and the temptation to stray from one's beliefs, while seeking divine help to stay steadfast and grounded in faith.
