This paragraph by A.B. Simpson meant much to me.
Some day even you, trembling faltering one, shall stand upon those heights that Joshua knew. As you look back upon all you have passed through, all you have narrowly escaped, all the perils through which He guided you, the stumblings through which He guarded you and the sins from which He saved you; you will shout, with a meaning you cannot understand now, Salvation to our God, which sitteth upon the throne, and unto the Lamb (Revelation 7:10).
