Supposing Him to be the Gardener. – John 20:15

But He answered and said, Every plant, which My heavenly Father hath not planted, shall be rooted up. Let them alone: they be blind leaders of the blind. And if the blind lead the blind, both shall fall into the ditch. – Matthew 15:13

In this great congregation many are to the Church what weeds are to a garden. They are not planted by God; they are not growing under His nurture; they are bringing forth no fruit to His glory. My dear friend, I have tried often to get at you, to impress you, but I cannot. Take heed; for one of these days, “supposing Him to be the gardener,” He will reach you, and you shall know what that word meaneth, “Every plant which My heavenly Father hath not planted shall be rooted up.” Take heed to yourselves, I pray.

Others among us are like the branches of the vine which bear no fruit. We have often spoken very sharply to these, speaking honest truth in unmistakable language, and yet we have not touched their consciences. Ah, but “supposing Him to be the gardener,” He will fulfill that sentence: “Every branch in Me that beareth not fruit He taketh away.” He will get at you, if we cannot. Would God you would turn unto the Lord with full purpose of heart; so that instead of being a weed you might become a choice flower; that instead of a dry stick, you might be a sappy, fruit-bearing, branch of the vine. The Lord make it to be so; but if any here need the caution, I pray them to take it to heart at once. “Supposing Him to be the gardener,” there will be no escaping from His eye; there will be no deliverance from His hand. As “He will thoroughly purge His floor, and burn up the chaff with unquenchable fire,” so He will thoroughly cleanse His garden and cast out every worthless thing. ~ C.H. Spurgeon
