Revelation 3:21 ESV
“The one who conquers, I will grant him to sit with me on my throne, as I also conquered and sat down with my Father on his throne.”

This promise was part of the letter to the Laodicea church, They were told that they were not hot or cold. Jesus exhorts them to become who they are supposed to be and become conquerers. Conquerers are fearless, brave, strong of heart and mind. If you will conquer the challenges of this life, you will sit down with Christ on His throne.
