If I commit a sin do I need to ask God for forgiveness again?

This question was one actually sent to me from a Facebook friend.  Thank you!

To answer this question let's take a look at the verse 1 John 1:9 - “If we confess our sins, He is faithful and just and will forgive us our sins and purify us from all unrighteousness.”  This verse tells us that we need to "confess" our sins, not ask for forgiveness.  The bible also tells us that if you have placed your faith in Jesus Christ for your salvation; then all your sins are forgiven. Now, I believe this means all your past, present, and your future sins no matter how big or small they were/are/or will be are forgiven. So how did I draw that conclusion?  Well in Colassians 1:14 and Acts 10:43 we are told that Jesus died to pay the penalty for all our sins, and when they are forgiven; they are all forgiven.  Keywords to remember there are "they are all forgiven."  So no I don't believe you have to ask God for forgiveness every time you have sinned; however, I do believe you have to confess your sin to God.  But why do you have to confess your sin?

Well think about it a minute.  If someone does a wrong against you, what happens with your relationship with that person.  There is a distancing between you and the other person; am I right.  What happens after the person admits they hurt you; you become closer because the person saw the error of his/her way allowing a healing between the two of you!  Well the same holds true with God.  All God wants with me and you is a relationship, but like any relationship there are going to be bumps and bruises that can/will hinder that relationship between me/you and God.  But when you confess your sin(s) to God you are admitting you are wrong and that you have sinned; and through this confession God will be faithful and just to you.  Faithful in that he will forgive your sin and just in that he will recognize that Jesus Christ already paid the penalty for that sin.  Also with your confession the distance between you and God is closed and the healing of your relationship and soul begins; all of these things draw you closer in your relationship with God, which is all he wants.

I remind you, God loves you for you and God is willing and wants a relationship with you.  The question I ask you is, are you willing?
