Proverbs 28:13 Reina-Valera 1960 (RVR1960)
13 He who conceals his sins will not prosper;
But he who confesses them and withdraws will obtain mercy.

What is missing can commit a child without his father knowing, just as we can commit sin without our Father and God see it.
He knows that we are only dust, but He expects us to be sincere and not to hide, nor to hide those things that his eyes clearly see; reason why the apostle Paul says in: Hebrews 4:13 (NKJV) 13 And there is no created thing that is not manifest in his presence; rather, all things are naked and open to the eyes of the one to whom we have to give an account.
And if you are naked that serves to hide it, assume your sin, your fault and put yourself to account before it is too late and you are reached by his right judgment, this understood King David when he said: Psalm 32: 5 (NKJV) My sin I declared to you, and I did not cover my iniquity. I said: I will confess my transgressions to Jehovah; And you forgave the evil of my sin. Selah.
Here is another reason to confess; We need your forgiveness, therefore, that this word encourages you to seek forgiveness and mercy, two signs of the love of God without which man can not achieve his purpose and above all eternal life.
