They do not have to cover up, for all Christians know that all Christians sin. There can be, therefore, a certain amount of openness, honesty, and relaxation about the relationships that Christians sustain to one another, especially in the home. What I am trying to say, however, is that Christians do not need to spend anxious hours of futile endeavor trying to cover their tracks. They do not need to think up ways to deceive the fellow next door into thinking that they are sterling specimens of humanity. With the freedom to admit the truth comes the possibility of repentance, and with repentance they can expect forgiveness and help from God and from one another.
Christians can progress rapidly out of sinful living patterns as a result.
They can pour their time and energies into the endeavor to replace sinful patterns with Biblical patterns of life. Rather than wasting time minimizing or denying the fact of sin, Christians can concentrate on dealing with sin. There is then no necessity to subject children to unusual and inappropriate discipline or to the excessive anger that sometimes grows out of embarrassment. No, not that at all. Rather, they will acknowledge sin for what it is and will proceed to deal with it in a Biblical manner.
