In this sermon from Ephesians 3, the pastor explores Paul's discussion of his calling and the stewardship of God's mystery. The mystery refers to how Gentiles can come to God through Jesus without becoming Jews first. The sermon emphasizes how believers demonstrate God's wisdom to spiritual authorities in heavenly realms through their lives and choices, even though they cannot see this realm.

The pastor explains that God's purpose in creating humans in His image was to have beings who would freely choose to love Him. Through Christ, believers have been restored to a position where they can demonstrate God's wisdom and glory in the spiritual realm through their faith and actions, even when no one else can see.

The sermon focuses on the concept of unity within the church, particularly through the lens of Ephesians 2. Pastor Osborne emphasizes that true unity in the church is rooted in Jesus Christ, not in cultural or social similarities. He explains how believers are part of God's household (family) and are built upon the foundation of the apostles and prophets, with Jesus as the cornerstone.

The message also explores how this family of God must follow both Old and New Testament principles, trust the Father even in difficult circumstances, and create an environment where God's presence is tangibly felt by visitors. The pastor stresses that the church's primary goal isn't numerical growth but rather being a place where God's presence is evident.

The sermon focuses on unity within the church, using the historical context of Jewish-Gentile relations in Ephesus to illustrate Paul's message in Ephesians 2. The pastor emphasizes how the blood of Jesus Christ broke down the walls of separation between Jews and Gentiles, creating one new unified body of believers despite their vast cultural differences.

The message transitions to modern-day application, challenging the common practice of separating church services by age or preference. The pastor argues that discipleship flows from old to young, and that maintaining unity across generations is crucial for authentic faith transmission and church growth.
