Yeh I agree,
I don’t think the issue for me is whether we confess or not.
The issue to me is of So why so and if not my not.
These issues have been talked about in the posts BillyG.
1) A couple of people suggest that since your already forgiven you do not need to confess your sins, as you now under no condemnation.
2) Most others suggest that although you are declared right with God (just) and therefore now under no condemnation, you still wrestle with the old man and we still sin. Sin disrupts our walking in harmony with God, he is Holy and Just. So we still confess our sins not from fear of condemnation (there is none for the believer) but rather to restore that filial relationship.
Both parties believe that we can only live the life of faith in the power of Christ by the indwelling of the Holy Spirit.
There is a 3rd group, those who are legalists, who believe in works righteousness, both groups would disagree with this.
What we need to understand is that some people have come to realization of what Jesus has done for us and it is all of grace, they may have been taught legalism, or just didnt fully understand salvation in Christ. I think we can see this in a couple of Posts above. However the danger is that this realization of grace does'nt take you from one error to the next, from one extreme to another. We should always remember the warning in Jude 1:4, that we do not pervert the GRACE of God.
Thats the basics. These issues are not new in the church. Legalism has always been around, and so has Antinomianism (hyper grace skirts dangerously close to Antinomianism).
So you have to ask yourself, what does the bible actually say, not what I or others say. Do we confess our sins or is a waste of breath as the Op suggests?
Me personally, even though I have been forgiven and now under no condemnation, I still confess my sins, and rely on the power of Christ to resist temptation etc.
(just as a note, read the statements to the churches in revelation...repent.) none of are perfected yet. But one day. Come Lord Jesus.
