An Achilles’ heel is a weakness despite overall strength, which can lead to a personal downfall. While the mythological origin refers to a physical vulnerability, idiomatic references to other attributes or qualities that can lead to downfall are common.
Do you ever go through an average day and feel beat up inside yet you’re not sure why? Look carefully at the interactions you’ve had with people throughout your day and you will clearly see the fiery darts of the enemy aimed squarely for your heart. When Satan attempts to bring someone into your life, there are arenas of operation. He does it to stop your spiritual walk with God. People with either deposit into your life or pull you down and subtract from your life. There is someone that is assigned to come into every life, into every marriage in a negative way to destroy it. There is someone sent to pull your children away from you, away from God.
The use of “Achilles heel” as an expression meaning “area of weakness, vulnerable spot”. Satan knows your weakness and he is aware of how and when to attack your vulnerability. The main way Satan attacks someone to destroy them, is through another person. When Abraham and Sarah had the promise of a son, both Abimelech and Pharaoh, when they saw Sarah, wanted her to be their wife. These were men that could have anyone they wanted and they wanted Sarah. She had to have been very beautiful. They would have interfered with the plan of God had not the Lord spoke to them and warned them not to touch Sarah. Then when Satan wanted to destroy Joseph, he sent Potifer’s wife, who couldn’t get him to sin, so she falsely accused him and got him thrown into prison.
The devil has one main goal: to turn us away from God. He will do everything he possibly can to achieve this goal. Temptation is certainly one of the devil’s main weapons — and it takes many different forms. He’ll try, for example, to tempt us with sins of the flesh — immorality, pleasure-seeking, destructive habits, and so forth. But if those don’t work he’ll tempt us with sins of the heart or mind — evil thoughts, wrong motives, anger, jealousy, and so forth. He’ll also attack us spiritually — trying to fill us with doubts, attempting to convince us that God doesn’t care about us, filling us with pride, and so forth.
Unbelievers, whether they are total strangers or people in your own home, are slaves to their sin and to the devil. They are merely pawns that Satan uses to full effect not only to keep people from learning the truth, but to oppress faithful believers in Jesus Christ. Satan who is the god of this age has blinded the minds of unbelievers, and the sinful mind is hostile to God. It does not submit to God’s law, nor can it do so. They cannot see the light of the gospel of the glory of Christ, who is the image of God. For we do not wrestle against flesh and blood, but against the rulers, against the authorities, against the cosmic powers over this present darkness, against the spiritual forces of evil in the heavenly places. Ephesians 6:12
The unsaved are not even capable of following Gods law in their unregenerate state. Our duty towards them is to forgive them, love them and pray for them, as well as share the gospel and shine the light of Christ in their lives. That is how the battle is won and how we turn the tide. Our battle is not against people, but this is a major avenue that Satan will use to wage warfare against your mind and heart. To counteract these attacks, we must put on the full armor of God and take our stand. We must realize this is a spiritual battle and that Satan is our real enemy. Ephesians 6:11
