We can be accused of a lot of things, but we should never be accused of lacking passion for prayer. Prayer without passion is heartless. It is the fervent prayer of a righteousness man that avails much (James 5:16).
The Holy Spirit comes as fire to dwell in us. When we are baptized we are baptized with the Holy Spirit and fire (Luke 3:16). Our charge is not to drum up fire, but we can cry out to the Holy Spirit to burn away the chaff in our lives that prohibits us from cultivating a passionate, fervent prayer life. When a man is passionately bent on intimacy with Jesus through prayer and purity, he or she will attain all the powerful graces that adorn the child of God.
