"OUR RULE IS THE COVENANT OF GRACE
"We must acknowledge that in the covenant of grace God requires the truth of grace, not any certain measure; and a spark of fire is fire, as well as the whole element. Therefore we must look to grace in the spark as well as in the flame. All have not the like strong, though they have the like precious, faith (2 Pet. 1:1), whereby they lay hold of, and put on, the perfect righteousness of Christ. A weak hand may receive a rich jewel. A few grapes will show that the plant is a vine, and not a thorn. It is one thing to be deficient in grace, and another thing to lack grace altogether. God knows we have nothing of our-
selves, therefore in the covenant of grace He requires no more than He gives, but gives what He requires, and accepts what He gives: 'If she be not able to bring a lamb, then she shall bring two turtle doves' (Lev. 12:8). What is the gospel itself but a merciful moderation, in which Christ's obedience is esteemed ours, and our sins laid upon Him, wherein God, from being a judge, becomes our Father, pardoning our sins and accepting our obedience, though feeble and blemished? We are now brought to heaven under the covenant of grace by a way of love and mercy.
"It will prove a special help to know distinctly the difference between the covenant of works and the covenant of grace, between Moses and Christ. Moses, without any mercy, breaks all bruised reeds, and quenches all smoking flax. For the law requires personal, perpetual and perfect obedience from the heart, and that under a most terrible curse, but gives no strength. It is a severe taskmaster, like Pharaoh's, requiring the whole tale of bricks and yet giving no straw. Christ comes with blessing after blessing, even upon those whom Moses had cursed, and with healing balm for those wounds which Moses had made."
