Even though the Scriptures tell us little about Satan’s origin, they do inform us that he is a fallen angel of considerable power. The New Testament describes him as a “great enemy” who “prowls around like a roaring lion, looking for someone to devour.” Jesus Himself said that Satan is such a force to be reckoned with that He is the only one strong enough to conquer him.
Jesus would go on to refer to Satan as the “ruler of this world.” Paul called him the “god of this age.” He also portrayed him as the head of a great, highly organized “army” of evil spirit beings. He is a cunning liar, capable of seducing Adam and Eve by disguising himself as an “angel of light.” The book of Revelation says that his powers of deception are so potent that he is able to lead the whole world astray.
While Satan is portrayed in the Bible as powerful, dangerous, and an adversary to be taken seriously, he shouldn’t be considered in any way equal to God. He is a creature with creaturely limitations. His power is nothing in comparison with that of the Creator of heaven and earth. And according to James 4:7, because of the power God gives to His children, if we submit to Him and resist the devil, Satan will flee from us. Although subtle and cunning, the devil is an already defeated foe who will continue to resist God furiously until the time that he will be sealed in hell forever.

Because this is a fallen world, we do nothing from entirely pure motives. (See article on Depravity.) As the prophet Isaiah said:
All of us have become like one who is unclean, and all our righteous acts are like filthy rags; we all shrivel up like a leaf, and like the wind our sins sweep us away (Isaiah 64:6).
Because our motivations are always imperfect and our choices often difficult, one of Satan’s most effective ploys is to confuse and paralyze Christians with his accusations, putting them out of effective action. As our accuser and enemy (1 Timothy 5:14-15; 1 Peter 5:8; Revelation 12:10), Satan delights in our anxiety and fear. Although we may intellectually accept the premise that no one merits God’s grace, Satan knows how to use our emotions to cause us to feel outside of the reach of God’s mercy. His accusations are often vague, indefinite, and persistent. They throb like a spiritual migraine. They torment us even after we have acknowledged known wrongs and asked God for forgiveness (1 John 1:9). Whenever we are overwhelmed by guilt feelings that aren’t traceable to a specific sin, or whenever feelings of condemnation persist even after we honestly confess them to the Lord, it is reasonable to assume that we are suffering from false guilt — guilt that is either coming from our own hearts or from our spiritual enemy.
Why can we assume that these feelings of condemnation are not coming from God? The Bible tells us that godly conviction is based on love, not fear. Its purpose is to instruct and to correct, not to torment. The apostle John wrote:
In this way, love is made complete among us so that we will have confidence on the day of judgment, because in this world we are like Him. There is no fear in love. But perfect love drives out fear, because fear has to do with punishment. The one who fears is not made perfect in love (1 John 4:17-18).
God is not arbitrary or cruel. He always convicts His children out of love (2 Samuel 12:13; Luke 15:10). Conviction is His tool to bring us to a deeper reliance upon Christ (2 Corinthians 7:10; Ephesians 2:1-10; 2 Timothy 1:9). His Spirit doesn’t overwhelm us with feelings of condemnation for sins that have been confessed and forsaken or for choices that are unavoidably troubling and ambiguous.
When we sin, we will have to live with the consequences of our actions and with the loving correction of the Lord if we do not correct ourselves. Our position as God’s children doesn’t shield us from responsibility. But the natural consequences of sin will never cause us to lose our family relationship with God or any of the spiritual security that Christ has given us.
We need to always remember that it is not our good works but the blood of Christ that has provided for our every spiritual need (Ephesians 2:4-10). Christ is the foundation of our spiritual freedom and our emancipation from fear. Christ is the reason that Christians, unlike unbelievers, have no need to deny or conceal their sins. The entire price for sins has already been paid by the Lord — which gives us reason to quickly confess any sin that would damage our wonderful family relationship with God (1 John 1:9).
When we get to heaven, the process of our spiritual perfection will be complete and our motives will be pure (1Corinthians 1 Corinthians 13:12; 15:49; Hebrews 12:22-23). But in this fallen world, we will always struggle with some legitimate feelings of guilt. Here we wrestle with the tension of knowing that everything we do falls short of perfection. But faith trusts God’s promises. It is willing to go forward in spite of uncertainty (Hebrews 11:1,6), to be a good steward of God’s gifts (1 Peter 4:10), and to be as fearless of God’s wrath as a child is of a loving Father (Matthew 25:24-26).
