John’s first letter was written not to help readers believe but to help them know they believe. It’s a message many of us need as we struggle to be sure that we really are saved or that we really are loved by God. When we need assurance, John’s letters are the place to turn to.

Unpacking these three short books verse by verse, pastor Sam Allberry helps readers to face the letters’ challenges and grow stronger in their faith, in the joyful certainty that they will always be God’s beloved children.

This expository guide is less academic than a traditional commentary and includes lots of application. It can be read from cover to cover, used in personal devotions or referred to as a resource for leading small groups or preparing sermons.
