Pray without ceasing. – 1 Thessalonians 5:17

Real prayers are constant prayers…Beware of prayers which leap up like a grasshopper and are soon down again. Let your prayers have the wings of a dove, let them fly away from earth and rest in God. Hypocrites pray by fits and starts, the genuine Christian “prays without ceasing.”

Beware of judging yourselves by certain spasms of prayer. When I put my lamp out last night, as I thought, it flashed up, then went down again, and yet again flashed up; it did so many times, as I stood waiting, but I knew it must go out ere long. Some have a way of flashing a prayer or two, but their piety is only a dying light, it will all be over soon. Continue instant in prayer, it shall be the test of whether your prayer is a lamp of the Lord or a dying light of your own kindling.

Beloved, we must continue in prayer, but the Holy Spirit alone can enable us to do it. We may, however, be much helped in it by occasionally setting apart a special time. Days of prayer and hours of prayer, and set seasons of prayer are very helpful. We ought to have our appointed seasons each day, but special times over and above our regular custom may stir the fire and enable it to burn more brightly. To unite with other Christians in prayer is often very helpful. Private prayer is more important than public prayer under any aspects, and is a better test of a Christian; still public prayer often reacts upon private devotion, and when two or three are together, and are agreed as touching the kingdom, their supplications will often be helpful to each other and obtain the thing which they desire. ~ C.H. Spurgeon
