My granddaughter won't make direct eye contact with those who she finds scary or unknown. She drops her head and looks at the floor. It doesn't change anything. The person is still there, but in her mind they are gone. Similar to the child who covers his eyes to hide from his parents when he is in trouble. If he can't see them, they can't see him.
Psalm 32 shows us another similar situation, only this time it is someone dealing, or in this case, not dealing with their sin. David begins the Psalm by expressing the joy and blessing of having forgiven sins.
"Blessed is the one whose transmission is forgiven, whose sin is covered.
Blessed is the man against whom the Lord counts no iniquity,
and in whose spirit there is no deceit."
It is a place of peace that the person whose is sin is covered resides in. It is only through forgiveness that this can be as all of us have sinned. (Romans 3:23) David is telling us that you are blessed when you acknowledge the sin in your life and then confess it so that you may be forgiven. The one "in whose spirit is deceit" is the one who does not acknowledge their sin. It may be by choice or by ignorance, but their refusal to take their sin to God for forgiveness will lead to problems.
"For when I kept silent, my bones wasted away through my groaning all day long.
For day and night your hand was heavy upon me;
my strength was dried up as by the heat of summer."
Note the physical affliction of holding onto sin. Nights spent tossing and turning. Days of your conscience tearing you apart. David knew this first hand as he had tried to conceal his own sin. He had personal experience with this attempt to "keep silent" about his sin. It does the same thing to us. When we think we can hide our sin and God won't find out it only leads us to pain and anguish. David is telling us here that this is NOT a place we want to be, and he is also telling us the only way to come out of this self-imposed affliction.
"I acknowledged my sin to you, and I did not cover my iniquity;
I said, 'I will confess my transgressions to the Lord,'
and you forgave the iniquity of my sin."
Acknowledge and confess your sin to the Lord. It is the only way that, as Peter says, times of refreshing may come. If you will just confess to Him your iniquity, He WILL forgive. (1 John 1:9) But it starts with you. Don't keep silent. Don't try to hide it. Acknowledge and confess your sin to Him. Return to the blessing of those whose sins are forgiven.
