Developing a Burden for the Lost

ESV Romans 9:1 I am speaking the truth in Christ– I am not lying; my conscience bears me witness in the Holy Spirit–
2 that I have great sorrow and unceasing anguish in my heart.
3 For I could wish that I myself were accursed and cut off from Christ for the sake of my brothers, my kinsmen according to the flesh.
4 They are Israelites, and to them belong the adoption, the glory, the covenants, the giving of the law, the worship, and the promises.
5 To them belong the patriarchs, and from their race, according to the flesh, is the Christ, who is God over all, blessed forever. Amen.
