Thomas Mockett (or Mocket) (1602-1670), was a puritan theologian and scholarly Reformed preacher of the Gospel. What does it mean to be a Christian who has forsaken the world for Jesus Christ? From various texts in Matthew 13 concerning the Kingdom of God and the incomparable excellency of Jesus Christ, Mockett teaches that every Christian should, and the wise Christian will, willingly part with all for Christ and the grace of the Gospel. He shows what it means to “part with all for Jesus Christ”, and what Christians “are to part with” for Jesus Christ. Anyone who does not forsake the world cannot be a disciple of Christ. This teaching is of utmost importance to the contemporary church, especially in today’s intolerant culture where status, goods and relations are often more important than the Gospel of grace, or the God of all grace, Jesus Christ.
