Hearing Jesus is Lord, especially in church settings, is quite common. Recently, I was hit with the wait of this. Jesus is King. That means He has authority, and it's changed for the better.
In the Bible, God names Himself as our Heavenly Father. It can seem a lofty title for someone unapproachable, but the opposite is true. When I began a relationship with God, He became the father that I never had had.
