God is the Great Missionary
God deliberately reverses the roles between himself and the Gentiles. It would normally be for them to ask, seek and knock (as Jesus was later to put it), and to adopt towards him the respectful attitude of a servant at his master’s disposal, saying, ‘Here I am.’ Instead, although they did not ask or seek or offer themselves to his service, he allowed himself to be found by them, he revealed himself to them, and he even offered himself to them, saying humbly to them, ‘Here am I.’ This is dramatic imagery for grace, God taking the initiative to make himself known.
This quotation is from Isaiah 65:2. “All day long” certainly refers to this present “day of salvation” or day of grace in which we live. While Israel as a nation has been set aside, individual Jewish people can be saved and are being saved. The phrase “all day long” makes us think of Paul’s ministry to the Jews in Rome when he arrived there as a prisoner. “From morning till evening” Paul expounded the Scriptures to them and sought to convince them that Jesus is the Messiah (Acts 28:23). Through Paul, God was stretching out His arms of love to His disobedient people, yearning over them, and asking them to return. God’s favor to the Gentiles did not change His love for the Jews.
God wants to use us to share the Gospel with both Jews and Gentiles. God can use our feet and our arms just as He used Paul’s. Jesus Christ wept over Jerusalem and longed to gather His people in His arms! Instead, those arms were stretched out on a cross where He willingly died for Jews and Gentiles alike. God is long-suffering and patient “not willing that any should perish, but that all should come to repentance” (2 Peter 3:9).
