Pastor Erik Lindeen's sermon titled "Set Free With a New Identity" explores the current identity crisis in our society, particularly among Generation Z. He argues that looking inward for self-discovery is flawed and offers a Christian approach to identity. Erik highlights that our identity is based on who God says we are, not our circumstances. Through faith in Christ, believers become sons of God and are united as one. He encourages embracing this new identity, rejecting negative self-talk, and supporting others in their journey of faith.
