Jesus came to save all people throughout the world. In His human life, however, He chose to minister specifically to the people of Israel. Among all cultures on earth, God's chosen people should have been able to recognize the Messiah. Despite this, He was despised and rejected by the very people who were supposed to love Him.
He was God incarnate, who, according to Israel's Old Testament scriptures, had come to dwell among His people. Their rejection of Jesus resulted in their rejection of the Father who sent Him. However, their rejection of Jesus fulfilled the prophecy of Isaiah, who wrote: 'Who has believed our message?' Although they rejected Jesus, they opened the floodgates of salvation for those who, on the opposite, received Him and put their trust in the wonderful name of Jesus. To those who believed in Him, He gave them the power to become sons of God.
While God may need to set aside His people, Israel, for a period of time, He has not abandoned His earthly inheritance. As Paul reminds us: for if the casting away of them is the reconciling of the world, what shall the receiving of them be, but life from the dead? (Romans 11:15) In other words, God uses both the good and the evil of this world to accomplish His sovereign will.

Dear Heavenly Father, I thank You so much that You sent Your only son, Jesus, to take on the role of our kinsman-redeemer. Thank You that in spite of our sinfulness and rejection of the Lord Jesus, You have completed Your work of salvation so that whoever believes in the name of the Lord Jesus Christ will be saved. You assured me that grace would help me in my time of need, and I know I can come to you. Thank you so much for being so deeply and intimately involved in this world. 
In Jesus's name I pray. Amen.
