And the Angel of God, who went before the camp of Israel, moved and went behind them; and the pillar of cloud went from before them and stood behind them. – Exodus 14:19

Earnestly I desire you to think of this. If you cannot see the Lord bright before you, and you are very dull and heavy, then, I pray you, look back and see how the Lord has helped you hitherto. Sit not down with your eyes shut but look back! Steadily observe the past! What see you there? Loving-kindness and tender mercy, and nothing else. As I look back upon my own past life-and I think I am not one by myself-I cannot discover, even with the quick eye of selfishness, anything of which I can complain of my God. “Truly God is good to Israel.” “His mercy endureth for ever.” Not one good thing hath failed; He has never left me, nor forsaken me. I have received blessings through my joys, and even greater blessings through my sorrows. The Lord’s way has been all goodness, undiluted goodness, all the while. I look back and see the light of His presence shining like the sun at noon; it is as a morning without clouds, I am overwhelmed with the boundless bounty of my God. I am unable to conceive of anything more kind than the heart of God towards His unworthy child. Well, then, God is not far away, if we look backward, He is there. He has been mindful of us; He will bless us. He gave us mercies yesterday; and He is the same today and for ever. The blessings of last night we have not forgotten; the blessings of this morning, are they not still with us? The fountain will not fail: it has flowed too long for us to raise the question. If there be no light breaking in the east, behold, it is lighting up the western sky. The Lord is evidently still behind us, and it is enough; for we can sing, “The Lord liveth; and blessed be my rock; and let the God of my salvation be exalted.” “He is my rock, and there is no unrighteousness in Him.” ~ C.H. Spurgeon
