To strive in prayer means to struggle through those hindrances which would restrain or even prevent us entirely from continuing in persevering prayer. It means to be so watchful at all times that we can notice when we become slothful in prayer and that we go to the Spirit of prayer to have this remedied. In this struggle, too, the decisive factor is the Spirit of prayer.
Ole HallesbyListen, my friend! Your helplessness is your best prayer. It calls from your heart to the heart of God with greater effect than all your uttered pleas. He hears it from the very moment that you are seized with helplessness, and He becomes actively engaged at once in hearing and answering the prayer of your helplessness.
Ole HallesbyWhen we go to our meeting with God, we should go like a patient to his doctor, first to be thoroughly examined and afterwards to be treated for our ailment. Then something will happen when you pray.
