- Observe the rule as faithfully as you can.
Jesus is referring to the rule of a Religious Order here. Most of us have made some vow before God and Church and we should be faithful our promises—i.e. Marriage vows and baptismal vows. Satan tempts to infidelity, lawlessness and disobedience. Fidelity is a weapon for victory.
- If someone causes you trouble, think what good you can do for the person who caused you to suffer
Being a vessel of divine mercy is a weapon for good and for defeating evil. The devil is about hatred, rage, revenge, and unforgiveness. Others have hurt us all at some time. What good can we do in return? Returning a blessing breaks curses.
- Do not pour out your feelings.
A talkative soul will more easily be attacked by the devil. Pour out your feelings to the Lord only. Remember, the good and evil spirits hear what you say aloud. Feelings are fleeting. Truth is the compass. Interior recollection is a spiritual armor.
- Be silent when you are rebuked.
Most of us have been rebuked at some time. We have no control over that but we can control our response. The need to be right all the time can lead into demonic traps. God knows the truth. Let it go. Silence is a protection. The devil can use self-righteousness to trip us up also.
- Do not ask everyone’s opinion, but only the opinion of your confessor; be as frank and simple as a child with him.
Simplicity of life can drive out demons. Honesty is a weapon to defeat Satan, the Liar. When we lie we put a foot in his camp and he will try to seduce us all the more.
