Adam Clarke's Commentary on the Bible

Verse 11 (1 John 5:11)

This is the record - The great truth to which the Spirit, the water, and the blood bear testimony. God hath given us eternal life - a right to endless glory, and a meetness for it. And this life is in his Son; it comes by and through him; he is its author and its purchaser; it is only in and through Him. No other scheme of salvation can be effectual; God has provided none other, and in such a case a man's invention must be vain.
