How do I know if it is sin?

On Wednesday evenings, we're studying "Living Holiness." Holiness is not just for the people attending this class. It is the goal of every person who calls himself a follower of Christ. You are either striving to be holy because God is holy (Leviticus 11:44; 19:2; 20:7 and 1 Peter 1:16) or you have determined to live in the self-life - or sin.

But how do you know if something is sin in your life? Well, for one thing what does the Bible say about it? To know this, you have to be reading the Bible. When someone has chosen to live in sin, I can almost guarantee that they've quit reading their Bible. They know, deep down they already know, that their behavior is against God's law. (See Romans 1:18-20)

Susana Wesley, mother of John and Charles Wesley, said this:

"Would you judge the lawfulness of a pleasure, take this rule: whatever weakens your reason, impairs the tenderness of your conscience, obscures your sense of God, or takes away the relish of spiritual things; whatever increases the authority of your body over your mind, that thing is sin."

Well said Susana!
