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

And I will rebuke the devourer for your sakes, and he shall not destroy the fruits of your ground; neither shall your vine cast her fruit before the time in the field, saith the Lord of hosts. – Malachi 3:11

I am sometimes troubled by the question, what if roots of bitterness should spring up among us to trouble us? We are all such fallible creatures, supposing some brother should permit the seed of discord to grow in his bosom, then there may be a sister in whose heart the seeds will also spring up, and from her they will fly to another sister, and be blown about till brethren and sisters are all bearing rue and wormwood in their hearts. Who is to prevent this? Only the Lord, Jesus by His Spirit. He can keep out this evil. The root which beareth wormwood will grow but little where Jesus is. Dwell with us, Lord, as a church and people: by Thy Holy Spirit reside with us and in us, and never depart from us, and then no root of bitterness shall spring up to trouble us.

Then comes another fear. Suppose the living waters of God’s Spirit should not come to water the garden, what then? We cannot, make them flow, for the Spirit is a sovereign, and He flows where He pleases. Ah, but the Spirit of God will be in our garden, “supposing our Lord to be the gardener.” There is no fear of our not being watered when Jesus undertakes to do it. “He will pour water on him that is thirsty, and floods upon the dry ground.” But what if the sunlight of His love should not shine on the garden? If the fruits should never ripen, if there should be no peace, no joy in the Lord? That cannot happen “supposing Him to be the gardener;” for His face is the sun, and His countenance scatters those health-giving beams, and nurturing warmths, and perfecting influences which are needful for maturing the saints in all the sweetness of grace to the glory of God. So, “supposing Him to be the gardener” I fling away my doubts and fears and invite you who bear the Church upon your heart to do the same. It is all well with Christ’s cause because it is in His own hands. He shall not fail nor be discouraged. The pleasure of the Lord shall prosper in His hands. ~ C.H. Spurgeon
