In Conclusion: The saved are in the church that belongs to Christ, not the ones that belongs to the d’evil where fallen angels (demons), humans or animals are adored or worshiped. Christ’s church – Congregation where the saved (Christ believer) and unbeliever get groomed to continuously grow in the act of learning, knowing, as well as obeying God’s Word. The Church of God is filled with individuals, meaning, … the foundation of God standeth sure, having this seal, The Lord knoweth them that are his. And, Let every one that nameth the name of Christ depart from iniquity. God Bless you
