New Defender's Study Bible Notes
7:3 end of life. This unique description surely implies far more than a mere failure to mention Melchizedec’s genealogy, as the standard naturalistic explanation of this passage has it. The only one of whom these statements could actually be true is God Himself, appearing to Abraham in a pre-incarnate theophany. God appeared to Abraham on other later occasions (e.g., Genesis 17:1; 18:1), but on this occasion, almost overwhelmed by the hostile, ungodly world around him, Abraham needed special comfort and encouragement from God. Thus the Lord (actually God the Son), appearing as the King of Righteousness (Revelation 19:11,16), the King of Peace (Isaiah 9:6), and the Mediator between God and Man (I Timothy 2:5), came to give Abraham His blessing (Genesis 14:19).
7:3 like unto the Son of God. No mere earthly king was ever “made like unto the Son of God,” nor was there ever one who “abideth a priest continually (same word as “forever”). It is difficult to see how these descriptions could be properly applied to anyone but the Lord Jesus Christ, who came to encourage Abraham in this unique pre-incarnate experience, assuming a human form “like unto” that which He would assume forever when He became the incarnate Son of God. For the first time He founded and implemented forever the priestly order of Melchizedec.
