How can God be sovereign while humans remain free or responsible? Study Acts 2, Pentecost, and the Bible’s teaching on providence and human choice.

In this in-depth Bible study, Allen Crostic explores Acts 2 and Peter’s Pentecost sermon with a focus on divine sovereignty, human responsibility, and the fulfillment of Joel 2 in the last days. The teaching examines how signs and wonders confirm Jesus as the Messiah, how the resurrection inaugurates the overlap of the present age and the age to come, and how God works through human choices without violating free will or causing sin. Drawing extensively from Acts 2:22–23, Acts 4:27–28, Romans 1, Exodus, and the precise wording of Westminster Confession of Faith 3.1 regarding the liberty and contingency of second causes, the lesson clarifies the Hebrew terms behind “harden,” the hardening of Pharaoh, the Egyptian background of heart imagery, and why divine foreknowledge does not eliminate genuine human choice. The study also engages philosophical theology, clarifying necessity versus contingency, highlighting the incompatibility of determinism with Scripture and genuine contingency, addressing the common objection that God’s foreknowledge negates free will, and distinguishing between God’s ideal and remedial will as well as strong versus weak actualization. This teaching is designed for viewers interested in Christian apologetics, biblical exegesis, philosophy of religion, providence, free will, and defending the coherence of Scripture’s teaching on God’s sovereignty, human accountability, and the nature of divine providence.
