No problem, let us consider this phrase carefully.The only Judaizer I know of us is our friend Jer15 who is an Ethnic Cleaner Judaizer. If you're surrounded by Judaizers in your congregation then you need to talk to them.
Notice the verse says "upon all them that believe". It doesn't say upon his elect. Therefore Belief comes before Righteousness and Regeneration.
"Unto all and upon all them that believe~
We agree the faith here is clearly our faith, as Paul returned to his introductory summary (1:16-17).
Our faith is the identifying and evidentiary mark that shows God’s righteousness upon us.
God’s righteousness is formally and forensically declared for believers (see 3:25-26).
The key point here is the repetitive use of all to classify all Jews and Gentiles together. The value is not on the two prepositions – unto and upon – but rather on the repeated all.
The message of the gospel and Scripture commands faith in Jesus Christ (Mark 1:15; Acts 8:37; 15:11; 16:31; 20:21; Gal 3:22; Ist John 3:23; etc., etc.).
The knowledge of and the assurance of eternal life begins with faith in Christ (John 20:31; Ist Jn 5:13; 2nd Peter 1:5). The very reason we have the written word of God, apart from God's testimony of spiritual truths we would never know, unless he had chosen another method to convey these truths to us, but he chose his written word preserved for us.
The scriptures are clear~Faith in Jesus Christ is the evidence of eternal life (John 5:24; 6:47; I John 5:4-5) ~not a condition on man's part.
There is no message of hope in Scripture to be held out for unbelievers (II Thess 1:8).
Again, faith is fruit of the Spirit, not a condition for the Spirit (Galatians 5:22; Luke 1:15; Isr Peer 1:21). Faith is the result of eternal and legal justification, rather than the condition or means.
Otherwise, the natural man who is at enmity against God and a condemned rebel must exercise faith as the condition!
We only obtain our faith through the righteousness of Jesus Christ who had perfect faith, and that's the very faith we live by in the flesh (2nd Peter 1:1; Galatians 2:20; etc.)
Faith follows regeneration, and regeneration must follow justification (Ist John 5:1). Those that believe are justified (passive, perfect), rather than shall be (Acts 13:39). Faith is an act of righteousness, and it must follow from righteousness (Ist John 3:7). We believe because Jesus Christ has already redeemed us from the law (Gal 4:4-6). Cornelius was accepted with God before he exercised faith in Christ (Acts 10:34-35).
Paul did not distinguish here between faith as evidence or faith as a condition for regeneration, but rather between faith in Christ and obedience to the law for justification.
The epistle of Romans, unlike that to Ephesus, does not deal much with regeneration; it must be assumed by the testimony and doctrine of the rest of the New Testament. However, the condition of all natural men just described (3:10-18) precludes decisional regeneration or decisional justification. Faith must originate with God.
The emphasis here is not the faith of Christ against our faith in Christ, but rather our faith in Christ’s work against any Jewish confidence in the works of Moses’ law.
Paul denied that faith is a work in Romans, for he was not opposing Arminians, who teach that God regenerates and justifies believers on the grounds of their faith. The epistle of Romans contrasts faith and law works; James profession and works.
Legal justification is God’s sovereign work (Rom 3;24; 4:5; 5:6-11,16-19; 8:29-34; 11:6). The gospel merely reveals justification (Rom 1:17; II Cor 5:18-21; 2nd Timothy 1:9-10).
Faith is our means of identification with Jesus Christ, whereby we know we have eternal life, are justified, and shall be justified in the sight of God in the great day to come.
Faith proves eternal life to oneself and others, so we preach faith in Christ (Ist Jn 5:13). To make our calling and election sure, we must believe … and more (2nd Peter 1:5-11). Paul taught conduct to lay hold on eternal life no different than faith (I Tim 6:12,19).
Faith will be set forth here and throughout Romans as a new principle, economy, system, “law,” basis, or so forth for hope of justification under the new covenant. Compare how works were the principle, economy, system, “law,” and basis for the old covenant.
Please consider: Paul used Romans for the nature of New Testament religion (faith vs. old covenant works), not the condition or means of regeneration or the ordo salutis of theologians. This same line of reasoning must be used to contrast the two covenants.
