What a restless being is a tempted child of God! How unable he often is even to rest locally, to take his chair, and sit quietly by his fire-side! Like Noah's dove, he can find no rest for the sole of his foot on the floating carcases of a ruined world. It is recorded of the prisoners, who in the first French revolution were awaiting in their dungeons the summons to the dread tribunal of blood, that some passed nearly the whole of their time in walking up and down their cells. So sometimes under trials and temptations, we pace up and down the room as if we sought to dissipate the exercise of our minds by the exercise of our bodies; or rush into the streets and fields to pour the heart out in sighs and groans, the restless mind acting and reacting upon the body.
And as an exercised child of God often cannot rest locally, so cannot he rest spiritually. He cannot rest in his own righteousness, nor in a sound creed, nor in a form of godliness, nor in the opinions of men, nor in anything that springs from or centres in the creature. There is always something uneasy, either in himself or in the ground on which he would repose. Sometimes it is strewed with thorns and briers; sometimes beset with sharp and rugged rocks. And yet, but for these restless, uneasy feelings, how many even of the Lord's own family would settle down short of gospel rest! Some would settle down in false religion; others in the world; some would make a god of their own righteousness; and others, like the foolish virgins, would securely sleep whilst their lamp was burning out.
But there is that restless, painful exercise where the life and grace of God are, that the soul cannot, if it would, settle down in any rest but that of God's own providing. "There remaineth, therefore, a rest to the people of God." That rest is Christ; the blood, righteousness, love, and grace of the Lamb of God.
