The main themes of John 4:1-42 are:

• God’s covenant mercies extend beyond the nation of
  Israel.
• The necessity of the New Birth, through the Holy Spirit,
  mediated through Jesus.

Five Lessons from Jesus the Evangelist

1. Jesus evangelized the marginalized sinners of society (1-
   9). So must we.
2. Jesus pressed the point to sinners that salvation turns
   on the Holy Spirit, mediated exclusively through him (10-
   14). So must we.
3. Jesus exposed the sinner’s sin, thus showing the
   necessity of the new birth (15-18). So must we.
4. Jesus pushed the exclusivist claim with sinners that the
   only worship God finds acceptable is “in spirit and truth”
   (19-24). So must we.
5. Jesus had a “ripe harvest” evangelistic outlook - an
   outlook that balances God’s sovereignty and human
   responsibility (35-37). So must we.
