John’s definition of sin brings the issue close to home. When we defend what God forbids or excuse what Christ commands us to forsake, we resist His authority. The sermon opens with John’s description of sin as lawlessness and considers what our response to sin reveals about our submission to God and to Christ as Lord.
The sermon then explains why a settled practice of sin is incompatible with the new birth. Jesus came to take away sins, free His people from slavery to sin, and make them children of God. Read alongside John’s earlier teaching on confession and Christ’s advocacy, this passage gives believers reason to confess their sins honestly and pursue righteousness with hope.
The sermon closes with Augustine’s account of his conversion, illustrating how Christ changes a person’s allegiance and response to sins once defended. The accompanying outline, listening guide, and reflection questions support personal Bible study, sermon preparation, and small-group discussion.
