In Romans 9, God chose Jacob for the purpose of carrying forth what God wanted, 1) that Jacob’s line would be a nation who stood above all other nations to show them God working in their lives; and 2) that the Messiah would come through Jacob, not Esau. Esau could have made better use of his life if he had sought God and obeyed Him.
May I add some Scripture that I feel that the Lord wants me to say to yours? Romans 10:8,9 and 10; that is, “But what does it say? ‘The word is near you, in your mouth and in your heart’ (that is, the word of faith which we preach): that if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved. For with the heart one believes unto righteousness, and with the mouth confession is made unto salvation.”
May I add this too? Romans 10:14-17, “But then how can they call upon Him in whom they have not believed? And how shall they believe in Him of whom they have not heard? And how shall they hear without a preacher? And how shall they preach unless they are sent? As it is written, ‘How beautiful are the feet of those who preach the gospel of peace, Who brings glad tidings of good things!’ But they (meaning Israel) have not obeyed the gospel. For Isaiah says, ‘Lord who has believed our report?’ So then faith comes by hearing and hearing by the Word of God.”
Here it is the responsibility of every person who hears the Word of God to say yes or no to Jesus becoming their Lord and Savior.
And one who some to Christ later in his life. Is that God's time for it, or just the one's choice? If our hearts are filled with the desire to serve God and find His kingdom, who are we to say this came about of us or God?
What is the source of the desire itself?
