"For thus saith the Lord God, the Holy One of Israel; In returning and rest shall ye be saved; in quietness and in confidence shall be your strength" (Isaiah 30:15).
Here is God's secret to spiritual strength: "Quietness and confidence shall be your strength." The word for quietness in Hebrew means "repose." And repose means calm, relaxed, free from all anxiety; to be still, to lie down with support underneath.
Not many Christians today have this kind of quietness and confidence. Multitudes are involved in a frenzy of activity, rushing madly to obtain wealth, possessions and pleasure. Even in the ministry, God's servants run about worrying, fearing, looking for answers in conferences, seminars, best-selling books. Everyone wants guidance, solutions, something to calm their spirit. Yet they seek it in every source except the Lord. They don't realize God has already spoken a word for them, through Isaiah: If they don't turn to him as their source, their striving will end in sorrow and confusion.
Isaiah describes what God's righteousness is supposed to accomplish in us: "The work of righteousness shall be peace; and the effect of righteousness quietness and assurance for ever" (Isaiah 32:17). If we're truly walking in righteousness, our lives will bear the fruit of a calm spirit, quietness of heart and peace with God.
As Isaiah looked around, he saw God's people fleeing to Egypt for help, trusting in men, relying on horses and chariots. Ambassadors were coming and going. Leaders were holding emergency strategy meetings. Everyone was in a panic, wailing, "What can we do?"
Isaiah assured them, "It doesn't have to be this way. Return from your backsliding. Repent of your rebellion of trusting in others. Turn to the Lord, and he'll cover you with a blanket of peace. He'll give you quietness and rest in the midst of everything you're facing."
