In Ephesians 6, Paul tells us to put on our armor in the battle against sin. This isn't a put on and take off armor but rather once we are adopted into God's family we are to be prepared for the war against sin. There is a battle raging behind the scenes "against the rulers, against the authorities, against the cosmic powers over this present darkness, against the spiritual forces of evil in the heavenly places" (12). We need to be ready at all times. The armor comes with shoes, belt, breastplate, helmet, shield and a sword.
The only offensive weapon mentioned in the armor is the sword. Paul tells us this is the sword of the Spirit, which is the word of God (17). God has given us his word so we might do battle against anything that is not pleasing in his sight. The Scriptures are sufficient for fighting sin. Josh Harris says, "Scripture cuts through the confusion and hazy half-truths that our sin generates. It reveals our wrong desires. It rebukes our apathy. It corrects our selfish human thinking. It unmasks the deception of sin. It points us to God's goodness and faithfulness when we're tempted to forget. It trains us in righteousness. It counters the false promises of lust with God's true promises."
Get in the word so you can do battle against sin and have life abundantly in Jesus Christ.
Grace upon grace,
