Blessed are ye that sow beside all waters… – Isaiah 32:0

Now, if I were to consider in my mind nothing but the natural depravity of man, I should never preach again. To preach the gospel to sinners, is as foolish a thing as to bid dead men rise out of their graves. For that reason, I do it, because it has pleased God, “by the foolishness of preaching, to save them that believe.” When I look upon the alienation from God, the hardness of the human heart, I see that old Adam is too strong for me; and if I regarded that one cloud of the fall, and original sin, and the natural depravity of man, I, for one, should neither sow nor reap. I am afraid that there has been a good deal of this, however. Many preachers have contemplated the ruin of man, and they have had so clear a view of it that they dare not say, “Thus saith the Lord, Ye dry bones, live.” They are unable to cry, “Dear Master, speak through us, and say, ‘Lazarus, come forth!’ ” Some seem to say, “Go and see if Lazarus has any kind of feeling of his condition in the grave. If so, I will call him out, because I believe he can come;” thus putting all the burden on Lazarus and depending upon Lazarus for it…If our Master bids us call him out from his grave, we can call him out, and he will come; not because he can come by his own power, but because God can make him come, for the time now is when they that are in their graves shall hear the voice of God, and they that shall hear shall live.

You know, from observation, that there are some persons who are much worse than others, some who are not amenable to kindness, or any other human treatment. They do not seem to be terrified by law or affected by love…There are such boys, and there are such girls, full of mischief, and levity, or full of malice and bitterness; and you say to yourself, “I cannot do anything with them. It is of no use.” Just so. You are observing the winds, and regarding the clouds. You will not be one of those to whom Isaiah says, “Blessed be ye that sow beside all waters.” ~ C.H. Spurgeon
