The Psalms have been the prayers of the Saints for generations. Many of us have not discovered this wealth of material for prayer. When you don’t know what to pray for as you should, or what kind of prayer to offer, the Holy Spirit is praying for you in groans too deep for words (Romans 8:26), and has also provided the groans of the Psalmists for our aid in prayer.
Use them as a guide to help you express the inexpressible.
Read through this chapter posted below. Psalm 20 is just one of 150 other masterpieces of prayer, praise, lament, song, meditation, and so forth. Pray through it slowly and write it out word for word if it helps.
