When someone loses a loved one, they mourn. They have lost that which they loved. We are called to sit with them, to love them, to comfort them in their period of mourning.
So, too, as we see our sinful hearts in light of a holy and righteous God, we mourn over our sin that separates us from God. We mourn as we seek forgiveness, to repent of our sins and seek mercy and grace at the feet of Jesus. As we lay our sins at Jesus’ feet and put our faith in Him and His sinless sacrifice at the cross, we are comforted. Jesus sends us the Holy Spirit to give us peace and joy as we put away our old self, our old desires and become a new creation. One that is wholly dedicated to serving God for our good and His glory. We now live a life that submits to His authority in our daily lives, trusting in His Word, His Truths, His Promises.
