I just finished studying 1 Peter. If you're interested, you can check out my notes I've posted on this blog :). This hymn/song seems like a perfect conclusion to my study. In 1 Peter, Peter tried to encourage the persecuted Christians to keep having a Christlike attitude, standing firm in the faith, pressing on as servants of God, entrusting themselves to the Just Judge, embracing an eternal perspective, and relying on God since we believers already have victory in Jesus and are guaranteed to receive the eternal glory after our perseverance through pain and sufferings. "Thanks be to God! He gives us the victory through our Lord Jesus Christ." (1 Corinthians 15:57) This song just makes me want to dance with joy :)! I hope your heart will be encouraged.
