01 - Introduction

The Bible teaches particular redemption and the free offer. But this raises a question: How can the two be reconciled? After all, they seem like a contradiction in terms. Let me spell it out. Take these as working definitions:
Particular redemption: Christ died to redeem the elect only
The free offer: God has revealed that the gospel preacher must invite and command all sinners to trust Christ, telling them it is their duty, and promising them salvation if they do
The seeming contradiction is self-evident, is it not?
