Bnonn Tennant on the necessity of "Unlimited" Atonement

This whole series is well worth your time.

Part 1: Particular atonement is inconsistent with what is revealed in Scripture about federal headship and forensic imputation: two doctrines central to Christ’s penal substitution.

 Part 2: Particular atonement is inconsistent with the universal gospel call, whether it is conceived of as an invitation, or as a command only.

Part 3: particular atonement provides no grounds for faith, and makes the assurance of salvation impossible.

 Part 4: Answering the objection that universal atonement requires that God be at cross-purposes with himself

Part 5: Answering the objection that universal atonement entails either universal salvation, or a double payment for sins

Part 6: Answering the objection that a universal atonement would not actually secure or guarantee salvation for anyone.
