God's plan of salvation was shrouded in mystery until Jesus came (Ephesians 3:8-12).  It was a half-understood secret which the Israelites thought was exclusive for them alone.  God, was their God; and they thought that He would only speak to them; even though He had already told Abraham that 'all peoples on earth will be blessed through you' (Genesis 12:3).  But part of the 'mystery of salvation', was that salvation through the death of Christ would be for all, Jews and Gentiles alike (Ephesians 3:6).
 
It was not that Gentiles had to become Jews in order to be confident of a glorious future with God.  No.  God's plan was that both Jews and Gentiles should see their future in Christ.  Indeed, Jesus said that real hope for an eternity with God is only found in Him (John 14:6).  

The Jews had looked for their Messiah, but did not recognise that their own Scriptures perfectly described the life and death of Jesus.  On the other hand, the Gentiles had no interest in the God of the Jews, but He was very interested in them!  The amazing truth is that every person who stops to listen to the gospel, irrespective of religious or cultural background, will have equal opportunity to receive Christ: and with Him, the hope of glory.
 
Although some think that all Western people are Christians, that is not true.  Alas, very many are not.  At the same time, many millions with totally different religious and social backgrounds have found the hope of glory when they heard the gospel and received Christ.  Jesus is for everybody (John 3:16).  To some people that is still a mystery, but you can always let them into the secret!  Let them watch www.crosscheck.org.uk: tell them how Jesus found you.  It is your privilege, as a believer in Jesus Christ, to unwrap the mystery of Christ to your family, friends and colleagues and encourage them to reach out to Him and be saved.  Today is the best day to start!
