VERSE 15. Brethren, I speak after the manner of men; Though it be but a man's covenant, yet if it be confirmed, no man disannulleth, or addeth thereto. After the preceding, well-taken argument, Paul offers another based on the similarity between a man's testament and God's testament. A man's testament seems too weak a premise for the Apostle to argue from in confirmation of so important a matter as justification. We ought to prove earthly things by heavenly things, and not heavenly things by earthly things. But where the earthly thing is an ordinance of God we may use it to prove divine matters. In Matthew 7:11 Christ Himself argued from earthly to heavenly things when He said: "If ye then, being evil, know how to give good gifts to your children; how much more shall your Father which is in heaven give good things to them that ask him?" To come to Paul's argument. Civil law, which is God's ordinance, prohibits tampering with any testament of man. Any person's last will and testament must be respected. Paul asks: "Why is it that man's last will is scrupulously respected and not God's testament? You would not think of breaking faith with a man's testament. Why do you not keep faith with God's testament?" The Apostle says that he is speaking after the manner of men. He means to say: "I will give you an illustration from the customs of men. If a man's last will is respected. and it is, how much more ought the testament of God be honored: 'In thy seed shall all the nations of the earth be blessed.' When Christ died, this testament was sealed by His blood. After His death the testament was opened, it was published to the nations. No man ought to alter God's testament as the false apostles do who substitute the Law and traditions of men for the testament of God." As the false prophets tampered with God's testament in the days of Paul, so many do in our day. They will observe human laws punctiliously, but the laws of God they transgress without the flicker of an eyelid. But the time will come when they will find out that it is no joke to pervert the testament of God.
