“My [only] sacrifice [acceptable] to God is a broken spirit; A broken and contrite heart [broken with sorrow for sin, thoroughly penitent], such, O God, You will not despise.”
You want a prayer answered? Stop and think about how big God is. He is so huge that He lives outside of this universe. He's the definition of power. Compared to Him, we look like little ants in the midst of billions of other little ants needing His attention. Being humble, broken, and having a contrite heart will certainly make Him hear and answer you. Sit with God and let Him change your entire scope of life. Pour into God with the right perspective.
