To have victory over sin we must call Sin it's worst possible name

If you act in hatred towards someone confess to the Lord "Lord, I murdered that person" If you gave in to lust 5 times today say "Lord, I am filthy, I committed adultery today with 5 different women" When we water down our sin by calling it something else, we remain in it. If you call hatred 'righteous indignation' for example instead of murder, you will remain in it.

 Let there be tears for what you have done. Let there be sorrow and deep grief. Let there be sadness instead of laughter, and gloom instead of joy. ~ James 4:9 ~

Yes, there will be those that say "you are forgiven, it's not right to live with a cloud over your head' Those people have much to be concerned about. Titus 1:15-17 tells us "To the pure, all things are pure, but to those who are corrupted and do not believe, nothing is pure. In fact, both their minds and consciences are corrupted. They claim to know God, but by their actions they deny him. They are detestable, disobedient and unfit for doing anything good, but as for you, communicate behaviour that goes along with sound teaching"

When you sin confess it immediately, and repent, and the laughter you turn to mourning, the Lord will then turn to joy.

I tell you the truth, you will weep and mourn while the world rejoices. You will grieve, but your grief will turn to joy. A woman giving birth to a child has pain because her time has come; but when her baby is born she forgets the anguish because of her joy that a child is born into the world. So with you: Now is your time of grief, but I will see you again and you will rejoice, and no one will take away your joy. In that day you will no longer ask me anything. I tell you the truth, my Father will give you whatever you ask in my name. Until now you have not asked for anything in my name. Ask and you will receive, and your joy will be complete. ~ John 16:20-24 ~
