We also respect God's silences as well as his sayings. We can trust him. The Bible does not say all we would like it to say. But it does say all that God wants to say and all that we need to know. (Letters To A Student, Drew, 60)
Psalm 46.10: Be still and know that I am God; I will be exalted among the nations, I will be exalted in the earth. The Lord Almighty is with us; the God of Jacob is our fortress.
Psalm 46 is a tumultuous time in the life of the Psalmist - mountains falling, waves roaring and nations in an uproar. But in the midst of tumult and chaos, God calls for quiet, stillness. Quietness is achieved not by looking for answers but by looking to God. Know this one thing: God is God. Period. Double period.
We are called to simply know who God is - that He will exalt His name and we must simply trust. Quietly trust God's moving among the nations, in the midst of turmoil and emptiness.
Be still and know - not the intimate details of God's hidden will - but the revealed character of God. He alone brings peace and stillness as God's people are surrounded by troubles and disappointments.
