This brother’s faith is quite active, so he often sees the Lord and seldom sees the devil - thank the Lord, this is a good thing; but the Bible tells us that we are not unaware of the devil. It’s a trick. The devil doesn’t let you see his existence so he can trick you, so you have to be careful! Be careful! We can clearly know from the Bible: First, the devil exists. Second, the devil uses various methods and tricks to hide his true nature and continues to tempt people. Third, the devil is so cunning that he can even disguise himself as an angel of light, so we must be very cautious. The Bible tells us to reject the temptations of the devil; to resist the devil and understand his schemes; to fight against him. This is the Christian's responsibility towards the devil.
Normally you don’t feel the existence of the devil. This is your negligence, because today there is so much sin, social corruption, and moral decay. These clearly tell us that people obey the leader of the power of the air, that is, For the evil spirits operating among the sons of disobedience, may the Lord continue to help you, give you confirmation from God, actively follow Him, and rely on the Lord’s power to understand Satan’s schemes.
