Feelings don’t define faith. Instead, faith is simply turning to the Lord. When you speak the psalms, you are “doing” faith. And remember that faith is the work of the Spirit of God in our hearts. As such, if you can speak psalms, God is near. With this in mind, persevere. Don’t just speak the prayers so that your depression can lift. Speak them because they are true and because they are evidence of Christ at work in you. Speak them often.
