Thus Scripture requires to be studied as a whole, and one part of it compared with another, if we are to obtain a proper apprehension of Divine revelation. The value of comparing Scripture with Scripture appears in the corroboration which is afforded. Not that they require any authentication, for they are the Word of Him who cannot lie, and must be received as such, by a bowing unreservedly to their Divine authority. No, but rather that our faith therein may be the more firmly and fully fixed. As the system of double entry in bookkeeping provides a sure check for the auditor, so in the mouths of two or three witnesses the Truth is established.
Scripture needs to be compared with Scripture for the purpose of elucidation.
Yet an appeal to the New Testament ought not to be necessary in order to expose the error of the other explanation, for the Law equally with the Gospel enjoined love to our neighbor and kindness to an enemy. So determined are some Arminians to deny the almightiness of God and the invincibility of His will that they have appealed to this passage in proof that the power of His incarnate Son was limited, and that there were occasions when His merciful designs were thwarted by man. Thus it was not any limitation in Himself, but something in them, which restrained Him. In other words, He was actuated by a sense of propriety. Comparison is useful also for the purpose of amplification.
