Based on Faith

The Greek preposition "ek" means out of or out from, and points to the origin of something. Out from faith refers to something based on faith, or more explicitly, based on God crediting our faith as righteousness. And what is that something? Salvation by being transferred into Christ where we undergo the washing of regeneration, rebirth as a new creation, and are then indwelt with the Holy Spirit. Thus all the blessings of salvation can be said to be "based on faith.!"

Romans 1:17, "...But the righteous one will live based on faith." I think walking according to our (credited) faith is in view here rather than salvation's blessings.

Romans 3:30, "since indeed God who will justify the circumcised based on faith and the uncircumcised through faith is one." Here I think the idea is New Covenant faith arises from Old Covenant faith for Jews, and arises without prior faith in God for Gentiles.

Romans 4:16, "For this reason [the promises to Abraham's heirs] is based on faith, in order that it may be in accordance with grace, so that the promise will be guaranteed to all the descendants, not only to those who are of the Law, but also to those who are of the faith of Abraham, who is the father of us all,

Romans 5:1, "Therefore, having been justified based on God crediting our faith as righteousness, we have peace with God through our Lord Jesus Christ,

Romans 9:30, "What shall we say then? That Gentiles, who did not pursue righteousness, attained righteousness, moreover the righteousness that is based on God crediting their faith as righteousness.

Romans 9:32, "Why? Because they did not pursue it based on faith, but as though they could by works. They stumbled over the stumbling stone,

Galatians 2:16
nevertheless knowing that a man is not justified based on the works of the Law but by means of Christ Jesus's faithfulness, even we have believed into Christ Jesus, so that we may be justified based on the faithfulness of Christ and not based on the works of the Law; since by the works of the Law no person will be justified. (Here, rather than our faith, the faithfulness of Christ is in view.)

Galatians 3:22
But the Scripture has shut up everyone under sin, so that the promise based on God crediting our faith in Jesus Christ as righteousness might be given to those who believe.

Galatians 3:8
The Scripture, foreseeing that God would justify the Gentiles based on God crediting their faith as righteousness, preached the gospel beforehand to Abraham, saying, “ALL THE NATIONS WILL BE BLESSED IN YOU.”

Galatians 3:24
Therefore the Law has become our tutor to lead us to Christ, so that we may be justified based on God crediting our faith as righteousness.

Galatians 5:5
For we through the indwelt Spirit, arising from God crediting our faith,as righteousness, are waiting for the hope of righteousness.

Those who are indwelt are the "we" of the verse. expectantly waiting for the hope of our righteousness at the second coming of our Lord.

Romans 10:6
But the righteousness that is based on faith says: "Do not say in your heart, 'Who will ascend into heaven?'" (that is, to bring Christ down)

 

The preposition "epi" is used in the same manner, but to be transparent, these verses could be translated "on the basis of" to differentiate between "ek" and "epi."

Acts of the Apostles 3:16
“And on the basis of faith in His name, it is the name of Jesus which has strengthened this man whom you see and know; and the faith which comes through Him has given him this perfect health in the presence of you all.

Philippians 3:9
and may be found in Him, not having a righteousness of my own derived from the Law, but that which is through faith in Christ, the righteousness which comes from God on the basis of faith,

 

One might pose the question, why does God's action arise from Him crediting our faith, rather than just our faith alone? Consider God taking positive beneficial action toward us based on not crediting our faith as righteousness. On the other hand we have Romans 4:4-5 and Romans 4:23-25 indicating God's beneficial blessings based on credited faith.

 

Romans 4:16, "For this reason [the promises to Abraham's heirs] is based on faith, in order that it may be in accordance with grace, so that the promise will be guaranteed to all the descendants, not only to those who are of the Law, but also to those who are of the faith of Abraham, who is the father of us all,

Here we see that the "descendants" of Abraham are not only some of his blood line descendants, but also includes those outside his bloodline who also believe, as credited by God's gracious choice.

 

Not only are God's blessings of salvation based on Him crediting our faith, but our actions in accord with His purpose and plan also arise from live or faithful faith. Many of these human actions can be found in Hebrews 11 which tells of OT Saints doing things "by faith."
