Jesus is better because Jesus is our Great High Priest.
The implications of this statement are at the heart of this letter to the Hebrews.
As the Eternal Priest, Jesus is the only mediator we may go through to access the Eternal God.
The power of His indestructible life introduces us to the better hope, the better covenant, we have whereby we draw near to God.
His power saves to the uttermost those who come to God through Him.
“And the Spirit and the bride say, ‘Come!’ And let him who hears say, ‘Come!’ And let him who thirsts come. Whoever desires, let him take the water of life freely.” (Rev 20:17)
