"Ah, Lord GOD! Behold, You have made the heavens and the earth by Your great power and outstretched arm. There is nothing too hard for You."

At the very time when the Chaldeans surrounded Jerusalem, and when the sword, famine and disease had desolated the land, Jeremiah was commanded by God to purchase a plot of land, and have the deed of transfer legally sealed and witnessed. This was a strange purchase for a rational man to make.
Common sense could not justify it, for it was buying with scarcely a probability that the person purchasing could ever enjoy the possession. But it was enough for Jeremiah that his God had bidden him, for well he knew that God will be justified of all his children.
He reasoned thus: "Ah, Lord God! you can make this plot of ground of use to me; you can rid this land of these enemies; you can make me enjoy the benefits of the land; for you made the heavens and the earth, and there is nothing too hard for you."
Whether it be a Noah who is to build a ship on dry land, an Abraham who is to offer up his only son, or a Moses who is to despise the wealth of Egypt, or a Joshua who is to besiege Jericho seven days, using no weapons but the blasts of rams' horns, they all act upon God's command, contrary to the dictates of human reasoning; and the Lord gives them a rich reward as the result of their obedient faith.
Would to God we had our Christian walk of these modern times a more potent infusion of this heroic faith in God. If we would venture more upon the naked promise of God, we should enter a world of wonders to which as yet we are strangers. Let Jeremiah's place of confidence be oursnfor othing is too hard for the God that created the heavens and the earth.
