You believe what you want to believe and I will believe in what I want to believe.
I believe what the Bible says, not what I "want to believe". But you certainly are free to believe whatever you want to believe.
Jesus died once for all and all sins.
Agreed.
Being a Christian, I have Christ in me and have fellowship whether I ask for forgiveness for each and every sin I commit or not.
Disagree. Forgiveness is the subject of 1 John. Otherwise, why did he mention it 4 times in 3 verses in the first chapter?
Fellowship speaks to the state or condition of a relationship, whether that of parent and child or husband and wife in a marriage.
While both relationships are permanent (at least that was God's design in the beginning regarding marriage), fellowship can either exist or not in either relationship.
When one party offends the other party, fellowship is broken.
The parable of the prodigal perfectly illustrates that principle. Throughout the parable, the prodigal was always a son, and the father was always the father. But fellowship was broken, which led the father to describe that as his son "was dead". But when the son confessed his sins and repented (returned to the father) fellowship was restored in that relationship. Leading the father to say this:
"for this son of mine was dead and has come to life again; he was lost and has been found.’ And they began to celebrate." Luke 15:24
The son didn't start out "spiritually alive", then died spiritually, and then came back to spiritual life again. It was fellowship between them that died and was revived.
For me, when or if I see a sin in me and, because I now I possess a repentant heart, I thank God for what is son has ALREADY done for me and is doing through me!...no matter what you may think, this is the truth....Romans 8:1!
The truth is that we as God's children are cleansed and forgiven our sins WHEN we confess them. Because that is exactly what 1 John 1:9 teaches.
How can you be filled with the Holy Spirit or walk by His means if you haven't confessed your sins?
What do you do when you grieve and quench the Holy Spirit? Even then, just thank God for what Jesus did? One MUST confess their sins for forgiveness.
Jesus taught this same principle to his 12 disciples in John 13 when He was trying to teach them humility by washing their feet. When He got to Peter, Peter said "no". And Jesus said, "unless I wash your feet, you can have no part of Me". This is a reference to fellowship, not relationship. We know that because Jesus made the issue clear after Peter responded by then saying "then not only my feet, but my hands and my head". Jesus replied "10 Jesus said to him, “He who has bathed needs only to wash his feet, but is completely clean; and you are clean, but not all of you.” 11 For He knew the one who was betraying Him; for this reason He said, “Not all of you are clean.” Jn 13
By telling Peter he was already "clean" He meant that Peter was already saved and didn't need another bath. But he did need to clean his feet after walking in the world (the roads of that day were filthy with animal feces).
It is impossible for one to have fellowship with another IF one's feet are covered in feces. That's why feet washing was a very practical practice in that day. To get the stench off so the visitor wouldn't stink up the house. And ruin fellowship.
