"...the oath he swore to our father Abraham: to rescue us from the hand of our enemies, and to enable us to serve him without fear in holiness and righteousness before him all our days."
The Gospel is better than you think. Don't take my word for it, listen to the words of The Holy Spirit through Zechariah. No longer do we live in fear of eternal condemnation for our sins. No longer must we strive with the burden of guilt. No longer are the days when sin and death reigned in our bodies, but now we have the knowledge of salvation through the forgiveness of sins.
It is no longer fear of punishment through the law that we are made holy and righteous. God has revealed himself through his tender mercy in the person of Christ Jesus. He has paid for every single sin past, present, and future in order that some may come to believe and glorify him.
The Gospel is better than we could have ever imagined. We have been enabled through the power of the Holy Spirit to serve God apart from the law. None is good but God and the Good News is that you cannot be good by working hard at it. God is good for you. You need only to give your life to Him and he will take care of the rest. When God looks on you, he sees not a sinner but Christ in you. Don't you believe that?
