The interesting aspect of this verse is that God cried out to His own people, Israel, to come to Him. What happened is that many other people, Gentiles, came to Him! God is thrilled when the people of this world hear about Him and desire to reach out to Jesus! But God is saddened that His own people, Israel, continue to ignore Him even though He calls out to them, "Here I am, here I am!"
Thank the Lord that you heard the Gospel of Christ and responded when you did! Truly God was gracious to you!
Pray for Israel, that they would be saved. Note what Paul said in Romans 9:1, "Brethren, my heart's desire and prayer to God for Israel is that they may be saved." Let's add our prayers to Paul's.
