Brethren, [with all] my heart's desire and goodwill for [Israel], I long and pray to God that they may be saved. ²I bear them witness that they have a [certain] zeal and enthusiasm for God, but it is not enlightened and according to [correct and vital] knowledge. ³For being ignorant of the righteousness that God ascribes [which makes one acceptable to Him in word, thought, and deed] and seeking to establish a righteousness ( a means of salvation) of their own, they did not obey or submit themselves to God's righteousness. ⁴For Christ is the end of the Law [the limit at which it ceases to be, for the Law leads up to Him Who is the fulfillment of its types, and in Him the purpose which it was designed to accomplish is fulfilled. That is, the purpose of the Law is fulfilled in Him] as the means of righteousness (right relationship to God) for everyone who trusts in and adheres to and relies on Him.

Salvation Is for All Romans 10.5-21

5For Moses writes that the man who [can] practice the righteousness (perfect conformity to God's will) which is based on the Law [with all its intricate demands] shall live by it. [Lev 18.5]

9Because if you acknowledge and confess with your lips that Jesus is Lord and in your heart believe (adhere to, trust in, and rely on the truth) that God raised Him from the dead, you will be saved. ¹⁰For with the heart a person believes (adheres to, trusts in, and relies on Christ) and so is justified (declared righteous, acceptable to God), and with the mouth he confesses (declares openly and speaks out freely his faith) and confirms [his] salvation. ¹¹The Scripture says, "No man who believes in Him [who adheres to, relies on, and trusts in Him] will [ever] be put to shame or be disappointed. [Ps 34.22; Isa 28.16; 49.23; Jer 17.7]"
