In this lesson from the All That Jesus Taught series, we examine the often-neglected command in Matthew 28:20—Jesus’ instruction to teach believers to obey all that He commanded. While much emphasis is placed on evangelism and baptism, true fulfillment of the Great Commission requires forming disciples who walk in lifelong obedience. This study challenges modern Christianity’s imbalance between conversion and discipleship, calling believers and church leaders back to the foundational mandate of teaching and living out every command of Christ.
