“I have written to you, young men, because you are strong, and the Word of God abides in you, and you have overcome the wicked one.” I John 2:14
Some years ago I read about a person with a very weak immune system that had to live in virtual isolation in a sterile room. Just going out in public and doing the things that a normal person does everyday could prove fatal for them. There was no going to the grocery store, to a restaurant, or simply riding around in a car for them. They were unable to do the basic things that we take for granted.
Similarly a Christian who has a weak spiritual immune system is open to attacks of the devil and demons. But when the Word of God abides in a Christian it causes them to be strong, to have a strong immune system spiritually. According to Strong’s Dictionary the word abide means, “To stay, continue, dwell, endure, be present, remain, stand, tarry, be thine own.” When we allow the Word of God to abide in us like that it causes us to be strong and to overcome the wicked one!
