Jesus' first coming was promised over 200 times in the Old Testament. The promise that Jesus will return for His followers is repeated 300 times in the New Testament. Not surprisingly - it is the most repeated promise in the New Testament.

There is a place more precious than any other, this side of heaven's door
A place where we love one another a shelter in time of storm
And thought it's a treasure, this home's not forever I long for the life that's waiting beyond
Where no one will ever be hungry or cold No one will hurt or will ever grow old
No one will die and leave someone along That's when I'll know I'm home
There is a place where truth will always be spoken and promises can be believed
A place where hearts can't be broken
and loved ones will never leave
So if you are longing for a place of belonging the home you've dreamed of is waiting for you
Where no one will ever be hungry or cold No one will hurt or will ever grow old
No one will die and leave someone alone That's when I'll know I'm home
Forever no pain or disease
all will be equal and all will be free
True love will come and we'll fall at his feet That's when I'll know I'm home.
- That's When I'll Know I'm Home, Geoff Moore

A disciple is someone who is following Jesus, being changed by Jesus, and is committed to the mission of Jesus.
