The Obedience (Works) Of Faith (Romans 1:5 and 16:26 John 6:28-29)

Our obedience is to the Gospel which is the result of God-given faith of, in and through the Son.
(Hebrews 12:2a; Hebrews 11:6; Matthew 3:17; Ephesians 2:8)

We believe the Gospel, thus we walk by faith in all we do, "I will show you my faith by my works" (James 2:18)
When we teach observance of the law (or any system of works) as having a part in our salvation, i.e. redemption, justification, sanctification etc. we are in reality being disobedient to the heavenly vision, and not walking by faith.

Galatians 3:
11 Now it is evident that no one is justified before God by the law, for "The righteous shall live by faith."
12 But the law is not of faith, rather "The one who does them shall live by them."

Matthew 3:
7 But when he saw many of the Pharisees and Sadducees coming to his baptism, he said to them, "You brood of vipers! Who warned you to flee from the wrath to come?
8 Bear fruit in keeping with repentance.
9 And do not presume to say to yourselves, 'We have Abraham as our father,' for I tell you, God is able from these stones to raise up children for Abraham.

Acts 26:
15 And I said, 'Who are you, Lord?' And the Lord said, 'I am Jesus whom you are persecuting.
16 But rise and stand upon your feet, for I have appeared to you for this purpose, to appoint you as a servant and witness to the things in which you have seen me and to those in which I will appear to you,
17 delivering you from your people and from the Gentiles--to whom I am sending you
18 to open their eyes, so that they may turn from darkness to light and from the power of Satan to God, that they may receive forgiveness of sins and a place among those who are sanctified by faith in me.'
19 "Therefore, O King Agrippa, I was not disobedient to the heavenly vision,
20 but declared first to those in Damascus, then in Jerusalem and throughout all the region of Judea, and also to the Gentiles, that they should repent and turn to God, performing deeds in keeping with their repentance.

Romans 4:3 For what does the Scripture say? "Abraham believed God, and it was counted to him as righteousness."

Galatians 3:7 Know then that it is those of faith who are the sons of Abraham.

James 2:

21  Was not Abraham our father justified by works when he offered up his son Isaac on the altar?

22  You see that faith was active along with his works, and faith was completed by his works;

23  and the Scripture was fulfilled that says, "Abraham believed God, and it was counted to him as righteousness"--and he was called a friend of God.

James is saying that Abraham’s obedience to God’s word demanding the sacrifice of Isaac is the fulfillment of the promise/covenant which God spoke to Abraham;

Genesis 15:

1  After these things the word of the LORD came to Abram in a vision: "Fear not, Abram, I am your shield; your reward shall be very great."

2  But Abram said, "O Lord GOD, what will you give me, for I continue childless, and the heir of my house is Eliezer of Damascus?"

3  And Abram said, "Behold, you have given me no offspring, and a member of my household will be my heir."

4  And behold, the word of the LORD came to him: "This man shall not be your heir; your very own son shall be your heir."

5  And he brought him outside and said, "Look toward heaven, and number the stars, if you are able to number them." Then he said to him, "So shall your offspring be."

6  And he believed the LORD, and he counted it to him as righteousness.

Hebrews 11:

17  By faith Abraham, when he was tested, offered up Isaac, and he who had received the promises was in the act of offering up his only son,

18  of whom it was said, "Through Isaac shall your offspring be named."

19  He considered that God was able even to raise him from the dead, from which, figuratively speaking, he did receive him back.

Abraham’s works of faith had nothing to do with adherence to the law (which had not yet been given) but an adherence to the promises, i.e. the word of God. How did Abraham know that God could raise the dead? He personally witnessed God’s ability to bring life out of death when he and Sarah were given the gift of a son though Sarah was long past the age of childbearing. (Genesis 18:10-15; 21:1-7)

Abraham could willingly, by faith, be prepared to sacrifice that which God promised, simply because God had promised it. Faith produces obedience in those who know that God is a God o0f his word, who keeps His word. The Lord promised descendants through Isaac, and Abraham took Him at His word.

Paul a true descendant/son of Abraham shared in this very same faith;

2Cor 1:

8  For we do not want you to be ignorant, brothers, of the affliction we experienced in Asia. For we were so utterly burdened beyond our strength that we despaired of life itself.

9  Indeed, we felt that we had received the sentence of death. But that was to make us rely not on ourselves but on God who raises the dead.

10  He delivered us from such a deadly peril, and he will deliver us. On him we have set our hope that he will deliver us again.

Thus Abraham walked in the God given faith of which Christ is both author and finisher, (which would include everything between beginning and end).

When Abraham did prove faithless, the Lord intervened. (Genesis 20)

2Timothy 2:

11  The saying is trustworthy, for: If we have died with him, we will also live with him;

12  if we endure, we will also reign with him; if we deny him, he also will deny us;

13  if we are faithless, he remains faithful -- for he cannot deny himself.

It is God’s faithfulness that produces the obedience of faith in His people.

Whatever is not of faith is sin. (Romans 14:23b)

Whatever is of faith is obedience. (2Thess 1:11-12)
