Repentance involves a posture. Repentance is not simply a one time act, but a lifestyle.
Martin Luther, a famous historical figure of the church was quoted as saying, 'All of life is repentance.' This was first on his list of 95 thesis, nailed to the door of the church leaders at the time.
The understanding of the Church at the time, was that repentance was something you did once a week, or month, in an organized confessional manner. Sometimes repentance is taught in a way that it is asking for forgiveness for something you've done wrong. It involves that, but it is not only that.
"I will give grace to the humble and will oppose the proud."
Repenting means that you are wrong, you are going in the wrong direction and need outside help. But it’s a posture, which means that it’s a way of life for you, not simply something you do once a week.
