Believing in Jesus is the only way to attain righteousness and become a citizen of heaven. There is no middle ground before God is either you are saved by Believing Jesus or you are not. There is no way to working out righteousness in Romans 10-1-3 this what Paul said.
10:1 Brethren, my heart's desire and prayer to God for Israel is, that they might be saved.
10:2 For I bear them record that they have a zeal of God, but not according to knowledge.
10:3 For they being ignorant of God's righteousness, and going about to establish their own righteousness, have not submitted themselves unto the righteousness of God.
If you read carefully you will notice they loved God and they did what the law says as much as they can but they were getting something wrong no man could keep the law. Most folks think the law is just 10, its far more than that we talking about over 600 laws how on earth can you keep all of them.
And living a good life without hurting any one does not make you righteous,keeping the law does not make u righteous either. The law was just a guide to keep the children of Isreal till when Jesus was manifest.
Paul calls it the schoolmaster.
Galatians 3:24 Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith.3:25 But after that faith is come, we are no longer under a schoolmaster.
You see you no longer need the law Jesus had come died and resurrected, You can't believe in God the Father without Believing in Jesus. Even if you keep all the laws you are still a sinner and you need to be born again because the law was not meant to make you guiltless before God and no one is justified through the works and rituals of the law.
Galatians 10:10-13 (Amplified version) And all who depend on the Law [who are seeking to be justified by obedience to the Law of rituals] are under a curse and doomed to disappointment and destruction, for it is written in the Scriptures, Cursed (accursed, devoted to destruction, doomed to eternal punishment) be everyone who does not continue to abide (live and remain) by all the precepts and commands written in the Book of the Law and to practice them.
11 Now it is evident that no person is justified (declared righteous and brought into right standing with God) through the Law, for the Scripture says, The man in right standing with God [the just, the righteous] shall live by and out of faith and he who through and by faith is declared righteous and in right standing with God shall live.
12 But the Law does not rest on faith [does not require faith, has nothing to do with faith], for it itself says, He who does them [the things prescribed by the Law] shall live by them [not by faith].
13 Christ purchased our freedom [redeeming us] from the curse (doom) of the Law [and its condemnation] by [Himself] becoming a curse for us, for it is written [in the Scriptures], Cursed is everyone who hangs on a tree (is crucified.
Jesus is the End of the law.
Romans 10:4 For Christ is the end of the law for righteousness to every one that believeth.
Stop working out your righteousness like the pharrisses because your righteousness cannot save you Hell may await you because of ignorance.
John 3:17 For God sent not his Son into the world to condemn the world; but that the world through him might be saved
John 3:18 He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.
All you need to do is Believe Jesus is the son of God who died and resurrected and and you will be saved.
