Romans 10  "Brethren, my heart's desire and my prayer to God for them is for their salvation." Oh yes!  This is our heart's desire and prayer for those we love too! But.. . Paul is praying this for those who were pursuing righteousness on their own merit.. those who were stumbling over Jesus.. those who had their sights on getting rid of this troublesome Paul..  Those who had the Law, but missed the Lawgiver's purpose and plan.. those who had zeal but no knowledge of God Himself. Those he loved but who wanted him gone.. 

"For Christ is the end (the goal) of the law for righteousness to everyone who believes."  This is the Good News that we have been  given. By faith we receive this gospel and are saved.. ".. if you confess with your mouth Jesus as Lord, and believe in your heart that God raised Him from the dead, you shall be saved; for with the heart man believes resulting in righteousness, and with the mouth he confesses, resulting in salvation." (v8-10) 

Gentiles have the same opportunity as the Jews, Paul teaches...the Lord is Lord of all and "whoever will call upon the name of the Lord will be saved."  But... 

"How then shall they call upon Him in whom they have not believed?

And how shall they believe in Him whom they have not heard?

And how shall they hear without a preacher?

And how shall they preach unless they are sent?"

"So faith comes from hearing and hearing by the word of Christ."  The Word has gone out across the world and some have received it with joy.. but others are "obstinate people" and refuse to listen.  And so.. we continue to pray.. 

Father in heaven,  I know some of those obstinate people.. they have heard the truth but have hardened their hearts and refused the grace so wonderfully offered.  Again we pray.. open their ears to hear and their hearts to receive the Truth.. that they might call upon the Lord and be saved.  This is our earnest prayer and our hearts desire, Gracious Lord.  Grant mercy to our loved ones.. the ones in our hearts right now.. that they might repent and call upon Jesus. We ask this in His name. Amen.
