I honestly believe God allows difficulty to come upon us, in order to bring us closer to Himself. It will not seperate you from Jesus, but cause you to cling more closely, more carefully, to Him.
We should abandon ourselves to God more fully at these times when He seems to have abandoned us. Let us instead attach ourselves to Him, and when He plunges us into the night, where pure faith is required, may we still press on through the agonizing darkness.
