This psalm opens by setting the stage for why the rest of the psalm is important. We are blessed because the Lord will forgive our sins, and for those that seek forgiveness, there is nothing that will provide more joy. Have you ever asked for forgiveness from someone in your life? If you were truly sorry, do you remember the wave of relief that came once you were forgiven? This is a feeling that cannot be replicated, it is a feeling of relief like no other, and when the Lord grants us forgiveness, this feeling of relief comes with an intensity that cannot be forgotten.
