The early church provides powerful examples of faithful and unfaithful giving through Barnabas and Ananias and Sapphira. Barnabas demonstrated Spirit-led generosity that became the foundation for his world-changing ministry, while Ananias and Sapphira's deception served as a warning about lying to the Holy Spirit. Faithful giving flows from three key principles: it's a disposition of the heart rather than a calculated decision, it's motivated by love for the church body rather than personal impulses, and it's directed by the Holy Spirit rather than driven by emotions. Our giving patterns reveal what we truly believe about God's ownership, provision, and trustworthiness. When we give faithfully like Barnabas, we position ourselves for greater ministry opportunities and align our hearts with God's purposes.
