After the king of Salem departs, the king of Sodom speaks with Abram, but this is an entirely different exchange.

21 And the king of Sodom said unto Abram, Give me the persons, and take the goods to thyself.

The king of Sodom, is in no position to make such a request. He has been conquered, first by Chedorlaomer and his confederates, then by Abram. Technically – all the spoils belong to Abram.

22 And Abram said to the king of Sodom, I have lift up mine hand unto the Lord, the most high God, the possessor of heaven and earth,

Abram has made a very solemn promise to God –

23 That I will not take from a thread even to a shoelatchet, and that I will not take any thing that is thine, lest thou shouldest say, I have made Abram rich:

24 Save only that which the young men have eaten, and the portion of the men which went with me, Aner, Eshcol, and Mamre; let them take their portion. Genesis 14: 21-24

As far as Melchizedek is an Old Testament “type” of Christ – the king of Sodom is most certainly a “type” of Satan. The Lord has revealed to Abram that the king of Sodom would be first in line to accuse him of coming by his riches dishonestly. How like the evil one – Satan is the “accuser of the brethren.” {Rev. 12:10} Throughout the Bible, Old and New Testaments – the Godly and the ungodly are always presented together.

1 After these things the Word of the Lord came unto Abram in a vision, saying, Fear not, Abram: I am thy shield, and thy exceeding great reward.

2 And Abram said, Lord God, what wilt Thou give me, seeing I go childless, and the steward of my house is this Eliezer of Damascus?3 And Abram said, Behold, to me Thou hast given no seed: and, lo, one born in my house is mine heir.

Abram wonders if God means to give him a son though his servant.

4 And, behold, the Word of the Lord came unto him, saying, This shall not be thine heir; but he that shall come forth out of thine own bowels shall be thine heir.5 And He brought him forth abroad, and said, Look now toward heaven, and tell the stars, if thou be able to number them: and He said unto him, So shall thy seed be.

Abram expresses his concern to the Lord. Yet another test – that resonates with us to this very day.

6 And he believed in the Lord; and He counted it to him for righteousness. Genesis 15: 1-6

What a high watermark in Abram’s faith! When he is first called out of Ur of the Chaldees to travel to an unknown land, he demonstrated complete trust and faith. It was challenging, but not impossible. But here – Abram is trusting in God to do what seems impossible.

Genesis 15:6 is the first record in Scripture of imputed righteousness. Genesis 15:6 is the foundation of the doctrine of justification by faith alone. Abram is Paul’s witness to salvation by faith –

“. . .faith was reckoned to Abraham for righteousness. . .Rom.4:9

There is only one plan of salvation in both the Old and New Testaments – FAITH. Old Testament saints looked forward in faith to the coming Savior, while we look back in faith to the Savior.

7 Know ye therefore that they which are of faith, the same are the children of Abraham.

8 And the Scripture, foreseeing that God would justify the heathen through faith, preached before the Gospel unto Abraham, saying,

In thee shall all nations be blessed.

Galatians 3: 6-8

***Important note:  Followers of Les  Feldick and other ministries which teach that Old Testament saints received another “gospel,” are grossly mistreating the Word of God.  Galatians clearly states that God Himself preached the Gospel to His friend Abraham in Galatians 3:8.  There is only ONE Gospel, and has only ever been ONE Gospel.
