It is in the dark that God is passing by. The bridge and our lives shake not because God has abandoned, but the exact opposite: God is passing by. God is in the tremors. Dark is the holiest ground, the glory passing by. In the blackest, God is closest, at work, forging His perfect and right will. Though it is black and we can't see and our world seems to be free-falling and we feel utterly alone, Christ is most present to us...
How my eyes see, perspective, is my key to enter into His gates. I can only do so with thanksgiving. If my inner eye has God seeping up through all things, then can't I give thanks for anything? And if I can give thanks for the good things, the hard things, the absolute everything, I can enter the gates to glory. Living in His presence is fullness of joy- and seeing shows the way in.
