You may not believe in the reality of Satan. If you do not, try resisting him! The Bible is clear in its description of this evil personality and it is a delusion to deny his existence.
Walter Brown Knight wrote: "God's children are engaged in an incessant warfare. Our adversary, the devil, is an implacable foe. In our warfare, no armistice can be declared. Some are lulled to sleep by the suavity and graciousness of false religionists who deny the existence of our adversary. It is hazardous for God's children to cease to be watchful and wakeful."
Satan's trail is traceable from the Garden of Eden to this present day. Sin and death are his trademarks, temptation his tool. Many become weary in the battle of resisting temptation. Perhaps you are one of those tired soldiers. If so, I have good news for you. There is a day coming when the devil will be unable to tempt anyone.
During the Kingdom of Christ on this earth, Satanic influence will be forbidden. This act reminds us that Satan's power is limited. We are not to be defeated and downcast. John put it well: "Ye are of God, little children, and have overcome them: because greater is he that is in you, than he that is in the world" (I John 4:4).
Whatever temptation is troubling you can be overcome: "There hath no temptation taken you but such as is common to man: but God is faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation make a tray to escape, that ye may be able to bear it" (I Corinthians 10:13).
Satan will be chained later. But even now, in Christ, we're free!
