You Are A Weapon of Righteousness!

When we unite ourselves, by faith, in the death and resurrection of Jesus Christ, we become weapons of righteousness. This is because our old self, the one that gets everything wrong, was done away with: nailed to a cross. We came up new. This new creation is a weapon of righteousness. It's our choice whether we unite with Christ or not. But, who wants to be a weapon of unrighteousness, anyway?

That's why Romans 6:13 says:

Don't go on presenting your members as weapons (opla) of unrighteousness to sin, but present yourselves to God, as alive from the dead, and your members as weapons (opla) of righteousness to God.

Your Bible probably reads something like this:

Do not go on presenting yourselves as instruments of unrighteousness to sin . . . , but . . .

This word translated as "instrument" in English is really "weapon" (oplo) in Greek. In English, it sounds better to call someone an instrument rather than a weapon. But, let's take it literally for a second; this is war, and when you unite with Christ you are a weapon against this darkness; you are a weapon of righteousness!
