Rom 10:1-4  "Brothers, my heart's desire and prayer to God for them is that they may be saved.  For I bear them witness that they have a zeal for God, but not according to knowledge.  For, being ignorant of the righteousness of God, and seeking to establish their own, they did not submit to God's righteousness. For Christ is the end of the law for righteousness to everyone who believes." (my notes: "End" as in completion, perfect example of the law- not abolishing of the law) God's righteousness consists in Absolute Sovereign Love. 
Only He determines ultimately. Rom 9:18  "So then he has mercy on whomever he wills, and he hardens whomever he wills." 


A zeal for God is not a ticket to heaven. In fact the zeal might simply be the result of lifting up ones own righteousness. You can not go about claiming to be working on behalf of God, doing His work, and in so doing you are breaking His commands. They are summed up in Love!. He is Absolute Love. 


Bombing, killing, destroying, hating in the name of God. Call it what it is-evil!


Rom 10:5-7  "For Moses writes about the righteousness that is based on the law, that the person who does the commandments shall live by them.  But the righteousness based on faith says, "Do not say in your heart, 'Who will ascend into heaven?'" (that is, bring Christ down)  or "'Who will descend into the abyss?'" (that is, to bring Christ up from the dead)." 


The law written on the heart does not rely on observances as a way to find favor from God. The heart of faith knows that all has been attained by Jesus. He has accomplished all righteousness on our behalf, by His death and resurrection, applied to us by faith that demonstrates itself in love. . 


Rom 10:8,9  "But what does it say? "The word is near you, in your mouth and in your heart" (that is, the word of faith that we proclaim);  because, if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved." 


It doesn't matter who you are or what your racial or religious background, only a heart that believes in and results in absolute love counts. 


Rom 10:10-13  "For with the heart one believes and is justified, and with the mouth one confesses and is saved. For the Scripture says, "Everyone who believes in him will not be put to shame." For there is no distinction between Jew and Greek; for the same Lord is Lord of all, bestowing his riches on all who call on him.  For "everyone who calls on the name of the Lord will be saved." 


If you call on Him, He will change your heart. He is Absolute Love.
