There is power in the blood of Jesus to forgive you from all your sins! The enemy fears this truth the most and that is why he attacks this teaching on the forgiveness of sins so vehemently. If the enemy can get you to believe the lie that you are not completely forgiven and keep you sin-conscious, he will be able to keep you defeated, condemned, fearful of God and caught in a vicious circle of failure.

We should work our salvation with FEAR and TREMBLING. We are ought to fear and love God.
Being sin-concious of a man is not a work of the enemy. IT IS THE PRIMARY WORK OF THE HOLY SPIRIT. He will always convict us if we had sinned when we are Christians. Fearing God is a lie?!! Fear God and Repent! Repentance is not one time job. It is a continuous work. Luke 15:10 used the present tense for the word repent. Being sin-concious is being Christ-concious. They are not different. Ye that love the Lord hate evil…
Dear Alvin – why exactly do those who are in Christ need to fear? What are we fearing? Surely not punishment (see 1 Jn 4:18). The Holy Spirit never convicts the righteous of their sins because their sin has been done away with (Jn 16:10, 1 Pet 4:1). Neither God the Father nor God the Spirit chooses to remember the sin that God the Son dealt with (Heb 8:12, 10:12,17). Yes, we should work out our salvation with fear and trembling – but we’re not fearing what you think we’re fearing. Sin-consciousness reveals a mind that has not appropriated grace. There’s no bad news in the good news.
If you study the root word of that which is translated as fear when it refers to the “fear of the Lord”, you will find that is not referring to being scared. Trembling yes, but not from terror, the root deep meaning of the word means to be overwhelmed with awe, almost to the point of paralysis. The trembling comes from the weight of God’s immense love as His goodness overwhelms us. There are certainly consequences for a believer committing an act of sin, but it has nothing to do with punishment. When we sin, we diminish the abundant life which is ours in Christ. Yes believers will be judged, to gauge the extent of their reward, not to determine atonement.
