Prayer has a distinct relationship to all Christian duties and graces. It is not possible for us to carry out the holy commands of our Lord Jesus unless we are abundant in supplication . . . Paul gives us first the warm antidote—”Rejoicing in hope,” and then he gives us the cool antidote, “Patient in tribulation.” Either of these, or both together, will work wonderfully for the sustaining of the spirit in the hour of affliction; but it is to be observed, that neither of these remedies can be taken into the soul except they be mixed with a draught of prayer. Joy and patience are curative essences, but they must be dropped into a glass full of supplication, and then they will be wonderfully efficient. How can we “rejoice in hope” if we know nothing about prayer to the God of hope?Whenever your hope seems to fail you and your joy begins to sink,—the shortest method is to take to your knees. By remembering the promise in prayer hope will be sustained, and then joy is sure to spring from it, for joy is the first-born child of hope. As for “patience,” how can we be patient if we cannot pray? Have not holy men of old always sustained themselves in their worst times of grief and depression by betaking themselves to prayer? Mind that you do the same. Impatience will be sure to follow prayerlessness, but the endurance of the divine will grows out of communion with God in prayer. (C . H. Spurgeon)
His divine power has given us everything we need for a godly life through our knowledge of Him Who called us by His own glory and goodness. Through these He has given us His very great and precious promises, so that through them you may participate in the divine nature, having escaped the corruption in the world caused by evil desires.
For this very reason, make every effort to add to your faith goodness; and to goodness, knowledge; and to knowledge, self-control; and to self-control, perseverance; and to perseverance, godliness; and to godliness, mutual affection; and to mutual affection, love. For if you possess these qualities in increasing measure, they will keep you from being ineffective and unproductive in your knowledge of our Lord Jesus Christ. But whoever does not have them is nearsighted and blind, forgetting that they have been cleansed from their past sins.
Therefore, my brothers and sisters, make every effort to confirm your calling and election. For if you do these things, you will never stumble, and you will receive a rich welcome into the eternal kingdom of our Lord and Savior Jesus Christ.
2 Peter 1.3-11
“The essence of lukewarmness is the statement, “I need nothing.” The lukewarm are spiritually self-satisfied. Don’t look into your head to see if you think that you are needy; rather, look at your prayer life.”
John Piper
