He presented himself alive to them after his suffering by many proofs, appearing to them during forty days and speaking about the kingdom of God. Acts 1:3
Jesus, after His resurrection, could have taught His followers a lot of things.
He could have told them what it was like to die. And then live again.
He could have explained the differences between a glorified body and the ones they still had.
He could have described the moment our sin debt was declared paid in full.
He didn’t.
The forty days He had with them, He spent speaking about one thing.
The kingdom of God.
That shouldn’t be a big surprise.
It’s the message He started with when He began His ministry. (Matthew 4:17)
The kingdom.
What it is.
How to live in it.
How to get more people in it.
If that was His message…
Shouldn’t it be ours as well?
