This sermon examines Revelation 2:1–7, where Christ commends the church of Ephesus for its labor, patience, and discernment but rebukes it for leaving its first love.

It calls believers to honest self-examination, wholehearted service, repentance, and offering God their best rather than leftover efforts, reminding listeners of their calling and the eternal reward for those who overcome.

This sermon explores the biblical metaphor of leaven as representing sin and false teaching, showing how its hidden, gradual influence corrupts individuals, the church, and the kingdom of God.

Using passages from Exodus, Matthew, and Paul’s letters, the message warns believers to remove leaven—sin and corrupt doctrine—to preserve holiness and truth.

Those who are born again by the Spirit of God, are “Not of this World.” 1Corinthians 5
