Prayer vs. Panic
Because the “Lord is near” we do not need to be anxious.
The three words for prayer are not significantly distinguishable; requests (aitēmata) are “made known” before God by prayer (proseuchē) and petition (deēsis). In so doing one acknowledges utter dependence on God while at the same time expressing complete trust in him.
Thus thanksgiving does not mean to say “thank you” in advance for gifts to be received; rather, it is the absolutely basic posture of the believer and the proper context for petitioning God. It is also the key to the affirmation that follows.
His comprehensive prohibition allows them no exception: nothing, absolutely nothing, is a proper object of the continuous stress of worry.
A comprehensive positive—but in everything—establishes a total contrast with the comprehensive negative—nothing. Only by praying with thanksgiving in every situation is it possible to stop being anxious about anything.
The peace of God denotes “the peace that God himself has.” In this sense, the peace of God refers to “the calm serenity that characterizes God’s very nature and that grateful, trusting Christians are welcome to share.” “Peace then is God’s very character; verse 9 refers appropriately to the God of peace.” Although the peace of God refers primarily to the peace God has and is in himself, the peace of God also refers to the peace that God gives: “the inward peace of the soul which comes from God, and is grounded in God’s presence and promise.”64
The peace of God is the opposite of anxiety.
The peace of God surpasses every human thought or device as a means of insuring tranquility of heart.” “God’s peace is able to produce exceedingly better results than human planning.”
